Hello and welcome to NewsHour, live from the BBC World Service in London.
I'm Rebecca Kesby.
It happened almost immediately after an hour-long phone conversation between Vladimir Putin and Donald Trump,
Russia's largest, most intensive air assault in the war so far.
Nearly every district of the capital, Kiev, was hit.
A record 539 drones and 11 missile strikes recorded by Ukrainian authorities,
also hitting Sumy and Kharkiv, as well as other areas.
Barely had the two presidents hung up their phones, did the strike.
begin.
Surely a sign that Mr Putin has not heeded Mr Trump's advice to end the war.
President Trump said he was disappointed.
President Putin repeated his insistence that what he calls the root causes need to be fixed,
which means territory and a limit on Ukraine's right to join alliances such as NATO.
Our correspondent in Kiev is Paul Adams.
He went out this morning to assess the damage of the attacks overnight.
The attack went on for hours.
Drones constantly buzzing in the darkness overhead,
air defence units frantically trying to shoot them down, hitting most but not all.
Well, that was a pretty long, interrupted night.
And as Kiev gets going this morning, you can see and smell what kind of night it was.
