More now from Zaporizhzhia, in the south, which came under renewed fire early this morning.

Twelve missiles hit public facilities, say emergency services - with one person killed.

Rescuers are said to have extinguished a fire which spread over 100 sq m (1080 sq ft).

A Telegram post from the regional governor adds the death occurred at a car dealership - with a school among other damaged buildings.

Russia is yet to comment on the latest strikes.

Nineteen people were killed by Russia's missile strikes on Ukraine yesterday, emergency services have confirmed.

In an update on Monday morning Ukraine's State Emergency Services also said 105 people had been wounded around the country.

As part of his nightly address on Monday, President Volodymr Zelensky filmed himself near recovery vehicles appearing to clean up one of the sites of the missile attacks

"Restoration work is currently under way across the country. We will restore all objects that were damaged by today's attack by Russian terrorists. It's only a matter of time," he said.

Zelensky added that Ukraine had managed to shoot down more than half of Russia's missiles and drones , but he also warned of the ongoing threat.

"Follow the safety rules and pay attention to air sirens. The danger is still here but we are fighting," the president cautioned.

Zelensky concluded his address by stating that Russia resorted to missile attacks because "they cannot oppose us on the battlefield"

"Well, let's make the battlefield even more painful for the enemy," he said.

Ukraine will continue its counter-offensive reclaiming land annexed by Russia in the south and east, despite yesterday's escalation of missile attacks, a senior politician has told BBC News.

Our diplomatic correspondent Paul Adams spoke with Ihor Zhovkva, deputy head of Ukrainian President Volodymyr Zelensky’s office.

Zhovkva said Monday's strikes were designed to cause panic, hitting major cities in the middle of rush hour.

But, he said, Russian President Vladimir Putin had failed to intimidate Ukrainians, even with the greater intensity of the strikes, which were seemingly targeted at both critical infrastructure and civilian targets.

Asked if he thought this would be Russia's tactic during the winter, Zhovkva agreed and said Russia planned to "fight against civilians rather than against soldiers".

Not a single military target had been hit during the three hour barrage, he claimed - although BBC News cannot independently verify that claim.

Asked if he felt the strikes would change how Ukraine fought, he said: "Ukrainian forces will go on with their counter-offensive."

For anyone in need a recap of yesterday's events, here's a summary of what happened:

• Widespread missile attacks on major cities across Ukraine, including the capital Kyiv, killed 14 people and dozens more were wounded, state emergency services said
• The Russian strikes took out the electricity in several regions, while water supplies in some areas were also compromised

• Russian President Vladimir Putin said the attacks were in response to what he has called a "terrorist attack" over the weekend, after an explosion damaged the only bridge linking Russia to occupied- Crimea
• US President Joe Biden condemned Monday's strikes in stark terms, saying they "demonstrate the utter brutality" of Putin's "illegal war"
• Among the damaged sites were residential buildings, schools, a nursery, healthcare institutions and a children's playground, Ukrainian authorities have said
• But Russian MP Evgeny Popov told the BBC that strikes on sites such as playgrounds were caused by Ukraine's air defences

• Former Russian President Dmitry Medvedev warned there would be more strikes to come and signalled the attacks might be the beginning of further Russian escalation

Leaders of the G7 group of advanced economies will meet virtually at lunchtime today to discuss Monday's barrage of attacks on Ukrainian cities.

During today's call, leaders including US President Joe Biden and UK Prime Minister Liz Truss are expected to re-state their support for Ukraine in its war effort.

Ukrainian President Volodymyr Zelensky is expected to attend as well.

A statement is expected after the call, and we'll let you know what they said then.

People in Ukraine are seeking shelter again this morning as air raid sirens have sounded around the country.

The threat of further bombardment comes just a day after Russia launched some of the worst attacks on the Ukrainian capital and other cities not near the front in months.

Our correspondent Hugo Bachega, who yesterday had to take cover during a live report - see below - as a result of incoming missile fire, is once again broadcasting from shelter in an underground carpark in Kyiv.

The southern Ukrainian city of Zaporizhzhia has been targeted with further missiles overnight, the regional governor has posted on the Telegram messaging app.

Oleksandr Starukh wrote just after 06:00 local time (04:00 BST) that Russia had struck infrastructure - adding that information about damage and casualties was still being ascertained.

Moscow is yet to respond.

Dozens of people have been killed in recent days during strikes in Zaporizhzhia, which was also targeted in Monday's widespread Russian bombardment of major Ukrainian cities.

Air raid sirens have gone off again across Ukraine this morning, a day after Russia launched some of the worst attacks there for months.

There are fears in the capital Kyiv that Russia could hit the country again and overnight more attacks have been recorded on the south-eastern city of Zaporizhzhia.

The G7 group of industrialised countries are due to hold a virtual meeting later to discuss the situation in Ukraine, which will also be attended by Ukrainian president Volodymyr Zelensky.

Meanwhile, the head of Britain's GCHQ intelligence agency is expected to give a speech arguing that Ukraine is turning the tide against exhausted Russian forces - who he will claim are running out of ammunition - and that Vladimir Putin's decision-making has proved to be flawed.

Stay with us.

This evening, at the end of a long, traumatic day, I spoke with Ihor Zhovka, deputy head of Ukrainian President Volodymyr Zelensky’s office.

He said this morning’s attacks were designed to sow panic, hitting major cities in the middle of rush hour. But, he said, Russian President Vladimir Putin had failed to intimidate Ukrainians.

He acknowledged that the missile strikes were more intense, resembling in some ways the early days of the war, but he sounded neither surprised nor phased by this latest escalation.

Critical infrastructure, including power plants and the electricity grid, were a particular focus of the strikes. Was this, I wondered, a sign of things to come this winter?

“Yes, I think this will be the tactic,” he said. “To fight against civilians rather than against soldiers.”

Not a single military target had been hit during today’s three hour barrage, he said. It’s not a claim we can independently verify.

“Today we are in the middle of October,” he said. “We are headed for winter and winter will be very difficult.”

I asked him whether the scale of Russia’s latest action meant the government here had any regrets about Saturday’s explosion on the Crimea bridge, which President Putin has blamed on Ukraine.

“I would not completely agree with you that this is a response,” he said. “This is not the first time Kyiv is hit by missiles, several times per day, massively per day.”

Kyiv has still not admitted having anything to do with the explosion on the bridge. Video which emerged on social media today showed for the first time the extent of the damage to part of the railway line, which is key to Russia’s ability to supply its forces in southern Ukraine. It’s likely to take some time to repair.

Would today’s events, I asked Mr Zhovka finally, change the course of the war?

Absolutely not.

“Ukrainian forces will go on with their counter-offensive,” he said.

Let's hear from Lord Richards now, who was the UK's chief of defence staff until 2013. He says Russia shouldn't be written off just yet.

"It’s an immensely large country with all sorts of raw materials, let alone man power," he tells Radio 4's World at One programme. "I really do think it would be early to say that Ukraine will win."

He says that the last thing Britain wants is a "drawn out war", warning:

"Diplomats need to get their act together."

Missile strikes across Ukraine caused blackouts across many areas of the country, leading to power outages and limited water supplies.

Lviv, in western Ukraine, was badly affected. Pictures showed the city plunged into darkness as night fell.

But as of now, 95% of the city's electricity supply has been reconnected, along with 70% of its water supply, according to the president's office.

An emergency session of the UN General Assembly has got off to an emotional start.

Ukraine’s Ambassador to the United Nations began his address by telling member states that his family in Ukraine had been in a residential area when it was attacked by the latest Russian missiles and they were unable to go to a bomb shelter. Russia had already killed some of his relatives, Sergiy Kyslytsya added.

He went on to call Russia “a terrorist state” and said it must be deterred in the strongest possible ways to prevent further atrocities. Their delegation, he said, left “a trail of blood” behind it whenever it entered the General Assembly hall.

Passionately, he told nations in the chamber that it was their responsibility to defend the principles of the UN charter and to vote in favour of the draft resolution before them that condemns Russia’s proclaimed annexation of four Ukrainian regions.

The emergency session of the United Nations General Assembly was called in response to the annexations, but it has been overshadowed by Monday's missile attacks.

Life goes on for many Ukrainians despite the destruction caused by widespread Russian missile attacks. Here's a few photographs we've picked out, taken after Monday's strikes.

We've got a bit more detail on the phone call that took place between Ukraine's President Volodymyr Zelensky and US President Joe Biden.

Earlier, President Zelensky said the two leaders had a "productive conversation", in which air defence was top of the agenda.

Now the White House has confirmed President Biden pledged to continue providing Ukraine with the support needed to defend itself, including advanced air defence systems.

Mr Biden also underscored his ongoing engagement with allies and partners "to continue imposing costs on Russia, holding Russia accountable for its war crimes and atrocities, and providing Ukraine with security, economic, and humanitarian assistance".

Russia launched a day of missile strikes across Ukraine on Monday, calling it retaliation for an attack on a bridge in Crimea on Saturday.

Explosions were heard across the country, including in Kyiv, Dnipro and Zaporizhzhia.

Ukraine says 14 people have died. Watch how the day unfolded in 60 seconds.

The UN General Assembly meeting has begun, hours after Russia launched missiles at cities across Ukraine.

While today’s debate may be overshadowed by the deadly attacks, this emergency special session on Ukraine was reconvened because of the Kremlin’s declared annexation of four partly occupied Ukrainian regions following so-called referendums.

The decision to bring the matter before the 193-member body was taken after Moscow used its veto in the Security Council on September 30th to block a draft resolution that condemned its proclaimed annexation.

Now, the General Assembly will vote on a draft resolution that stresses these actions have no validity under international law. More than 60 nations will speak before a vote is held in the coming days. With the United Nations, though, nothing is ever simple.

The chamber began the session with a procedural vote on whether there would be a recorded vote or, as Russia wanted, a secret ballot on the draft resolution. One-hundred-and-seventy members voted in favour of holding a recorded vote after the debate, enough for the measure to pass and another blow to Moscow.

A Ukrainian emergency responder has been speaking to the BBC after a day of heavy Russian strikes.

He says the first place he went to help people earlier was near a university in Kyiv that one of his friend studies at.

"There were massive casualties - around 10-15 people," Alexander says, explaining he then went to the centre of the city to help as many people as possible.

He said he later attended the scene at a business centre, where around 20-30 people were lying on the groun. He said some had lost legs, others had shrapnel injuries. "It was pretty hard for us to work with that amount of people," he says.

He says one of the hardest things about today was the fact so many victims were women and older people. "These are just civilians who were walking around the city and were so close to dying," he says.

Alexander also says there were lots of people he met who' had fled from other parts of Ukraine - including the now annexed Donetsk and Luhansk - only to be bombed in Kyiv.

Insisting that the sites hit were civilian ones, he says there was no military activity near any of the scenes he attended. "Today was hard, people are really afraid," he says.

President Zelensky has tweeted that he has had conversations with the leaders of the UK, US and Canada and that he tackled the issue of air defence with all three.

"Ukraine needs an air shield to protect civilians and critical infrastructure," Zelensky said he told Canada's Justin Trudeau.

Ukraine's president said he also had a "productive conversation" with President Biden, adding that "air defense is currently the number one priority in our defense cooperation" and urging "US leadership with the G7's tough stance".

And, as we reported earlier, Zelensky told the UK's Liz Truss that he counts on "the UK's leadership in consolidating international political and defense support for Ukraine, in particular regarding the protection of our skies".
