As it happened: Kyiv warned of toxic fumes after strike on oil depot - BBC News
Residents of the capital are urged to close windows - but many are already sheltering underground.
Tonight, at this midnight hour, stark warnings sound of an imminent onslaught against the heart of Kyiv.

“In 30-60 mins #Kyiv will be under attack never seen before. #Russia will hit us with all they have,” tweeted MP Lesia Vasylenko.

Air-raid sirens have pierced the darkness, amplified by warnings in buildings and neighbourhoods for residents to immediately take to shelters. This is already a city where life has dropped underground, to basements, bomb shelters, and metro stations-turned-bunkers. A strict curfew is in force until 8am on Monday.

There’s been a chilling quiet these last three days in the heart of Kyiv. An eerie stillness on emptied streets has been shattered by occasional crackles of gunfire, a thud of artillery and a thunder clap when missiles land in the distance, on the edges of a beleaguered capital.

A Russian invasion, now at the end of its third day, has seemed to stall on the edges of the city in the midst of concerted Ukrainian resistance – soldiers guarding city gates, civilians taking up arms, even taunting Russian soldiers as they advance in their tanks and armoured vehicles.

Reports from Moscow in recent hours spoke of orders to advance on the city “from all directions.”

In the dead of a Kyiv night, there’s an ominous sense that the battle for this city is about to be unleashed.
