Watch: BBC on scene as rescue mission begins in Kyiv
Here's some footage of three Russian strikes that hit Ukraine's capital in the early hours of today.
The overnight strikes mainly hit residential areas in the city, and the current number of confirmed deaths is 17.
Our next post, from BBC Verify, will explain the video in more detail.
CCTV captures moments three strikes hit Kyiv
As we've been reporting, several areas in Ukraine's capital Kyiv were impacted by Russia's overnight strikes.
The map below shows just how widespread the damage has been. Let's take a closer look:
Damage was also recorded in Desnianskyi and Obolonskyi, officials say.
The Russian ambassador to the UK has arrived at the Foreign Office in London.
Andrey Kelin was seen getting out of his car in Westminster after he was summoned over Moscow's overnight strikes on Kyiv, which hit the British Council offices.
Less than 15 minutes after his car pulled up, he was spotted leaving.
To "summon" an ambassador is one of a few diplomatic tools a country has when it wants to make its anger felt to another country.
When an ambassador is summoned, a diplomatic note is sent to the relevant country's embassy asking its representative to attend a meeting at the foreign ministry.
The medium of the summoning is the message, John Casson, former UK ambassador to Egypt told the BBC in 2019.
"The main thing is that it is a piece of diplomatic theatre and everybody understands their role, and acts their role," Casson said.

In a post on social media, David Lammy notes Moscow's strikes "killed civilians, destroyed homes and damaged buildings, including the British Council and EU Delegation in Kyiv".
"We have summoned the Russian Ambassador. The killing and destruction must stop," he says.
The number of people killed in Kyiv following Russia's overnight strikes on Ukraine's capital has risen again.
At least 17 people - including four children - have died, according to Ukrainian officials.

The overnight attacks hit the bloc's offices in Kyiv, causing damage to the building but no injuries to staff.
Kallas said the attack showed Russia had made a "deliberate choice to escalate and mock the peace efforts".
Russia's ambassador to the UK is to be summoned by the Foreign Office after major strikes on Kyiv overnight.
It is expected Andrey Kelin will meet officials, not ministers.
At least 15 people were killed in a wave of strikes on Ukraine's capital overnight, and the offices of the British Council were damaged.
UK Prime Minister Keir Starmer earlier accused Russia of "sabotaging hopes of peace" with its "senseless" attacks.

We’ve been looking at images from the latest wave of Russian strikes against the Ukrainian capital Kyiv.
The attacks have killed at least 15 people including four children, according to Ukrainian emergency officials.
Local authorities have not confirmed where the strikes took place. But we’ve located video of damage to housing complexes in Kyiv’s Holosiivskyi and Darnytskyi districts.
European Council President António Costa has confirmed that the office of the EU’s delegation to Ukraine was also hit.
We’re continuing to investigate these and other strikes across Ukraine and Russia and will provide updates throughout the day.
Russia's ministry of defence has just released its latest operational update on its war in Ukraine.
It says Russian forces struck military targets in the Sumy, Donetsk, Zaporizhzhia, Dnipropetrovsk, Kherson, and Kharkiv regions.
Among the targets were ammunition depots and unmanned aerial vehicles, as well as temporary deployment points of Ukrainian armed forces.
The ministry adds that it hit a medium reconnaissance ship in the Danube river, and its air defences shot down aircraft, aerial bombs, rocket projectiles and unmanned aerial vehicles.
There is no mention of its overnight strikes on predominantly residential areas of Ukraine's capital Kyiv, in which 15 people, including four children, have been killed.

Russia launched a major overnight attack on Ukraine's capital Kyiv. If you're just joining us, here's what you need to know:
And, the BBC is reporting from the ground in Kyiv - here's the latest from Katy Watson on the aftermath of last night's strikes:
Rescue mission begins after Russian attack on Kyiv

Reporting from Kyiv
I found Oksana Rumpik, 54, and her husband Mykhailo Rumpik, 57, picking through their car outside a destroyed building.
Luckily, it was parked in the row furthest from the blast, so much of the damage done was only broken glass.
The couple were getting ready to go on a fishing holiday at the weekend - but in a country at war, regular plans have to change.
They tell me their neighbour's son lived in the building that was hit, along with his wife and baby. There’s no word of where they are now.
Peace is only possible without Putin, Mykhailo tells me.
"But he wants to be president," he says wistfully. The anger he feels towards Russia is clear.

The deadly Russian blend of drones and missiles is all too familiar to Ukrainians - but last night’s attack was, in the words of one official, “peculiar”.
It’s the first time Kyiv has been majorly hit since Donald Trump hosted Vladimir Putin in Alaska a fortnight ago.
Back then, Russia’s leader was greeted with applause, and the US president subsequently claimed “Putin wants to make a deal for me”.
These strikes reinforce Europe’s argument that the Kremlin is not interested in peace, and there will be continued calls for Trump to get tougher with Moscow.
Until now, Trump has resisted further sanctions, though has followed through with even higher tariffs for India, a major buyer of Russian oil.
He has often voiced his frustration with Russian airstrikes - but for the Ukrainian cities on the receiving end, it’s not been enough to stop them.
Image source, Getty ImagesAs we reported earlier, the EU's diplomatic building in Kyiv was hit by Russia's overnight strikes.
European Commission President Ursula von der Leyen says she is "outraged by the attack on Kyiv also hitting our EU offices. This was the deadliest drone and missile attack on the capital since July... it was attack also on our EU delegation."
"I just spoke with our deputy ambassador and I'm relieved that none of our staff were harmed."
In an earlier post on X, von der Leyen described the attacks on Kyiv as "another night of Russia’s relentless bombings".
She warned that "Russia must stop its indiscriminatory attacks on civilian infrastructure immediately" and calls for Putin to "join negotiations for a just and lasting peace".

Image source, ReutersWe're starting to hear some reaction from EU officials following Russia's strikes on Kyiv - we'll bring you some of that in our next few posts.
Kaja Kallas, the European Commission's vice-president, has accused Russia of deliberately escalating the conflict in Ukraine and mocking ongoing peace efforts.
"While the world seeks a path to peace, Russia responds with missiles," she wrote on X.
"The overnight attack on Kyiv shows a deliberate choice to escalate and mock the peace efforts. Russia must stop the killing and negotiate."
Kallas is referring to ongoing attempts at peace negotiations between Russia and Ukraine, mainly mediated by the US.
Kallas is also the commission's High Representative for Foreign Affairs and Security Policy - meaning she is responsible for strengthening Europe’s security and defence - something this war threatens.

US special envoy Steve Witkoff will meet representatives from Ukraine in New York tomorrow for talks on the war.
Zelensky’s chief of staff Andriy Yermak and security council chief Rustem Umerov will attend from the Ukrainian side, according to local media reports.
In a video posted on social media, Zelensky says the meeting will discuss the "military, political and economic components of security guarantees" for Ukraine.
"The task is to move as fast as possible, so that this too becomes a lever of influence," he says.
Zelensky and US President Donald Trump discussed a security guarantee for Ukraine at a summit in Washington earlier this month.
In an interview with Fox News on Tuesday, Witkoff said the talks would send a "big signal".
He also said the US is in daily contact with Russia.
We've just received another update on the death toll following Russia's overnight strikes on Kyiv.
Tymur Tkachenko, the head of Kyiv's military administration, says 15 people have died, including four children.
Search and rescue operations are continuing in the Darnytskyi district, he says.
Image source, EPAThese overnight attacks come against a backdrop of diplomatic efforts to end the Ukraine war.
But three and a half years after Russia's full-scale invasion, fighting on the ground shows no sign of abating.
"Russia still does not fear the consequences," Ukrainian President Volodymyr Zelensky said about the overnight strikes on Kyiv.
The latest international effort to achieve a ceasefire in Ukraine was launched by US President Donald Trump earlier this month. He met his Russian counterpart, Vladimir Putin, in Alaska, before meeting Zelensky with European leaders in Washington.
Trump has been pushing for a Putin-Zelensky summit. Ukraine's president has backed the move, but he has sought security guarantees from Western allies to prevent any future Russian attack in the event of a peace deal.
Zelensky has said Ukrainian and US officials will meet in New York on Friday as part of intensified mediation efforts to end the war - we'll have more on that meeting shortly.

Elsewhere in Ukraine, Russian attacks continued, resulting in civilian deaths.
Ukraine's National Police report that three people have been killed by Russian artillery fire in frontline areas of the southern Kherson region: an 83-year-old woman in the city of Kherson itself, and a man and a woman in the village of Novovorontsovka, aged 47 and 49.
More people were injured in drone and artillery attacks on central parts of Kherson, the police said.
And in the frontline town of Kostyantynivka, two civilians have been killed in continuing Russian attacks involving glide bombs, drones and artillery, police say.
