Ukraine has shown reporters fragments of the missile it says hit a key government building in Kyiv this weekend, identifying it as a Russian Iskander cruise missile.
Officials here now believe the building was struck deliberately in the early hours of Sunday morning.
Vladimir Putin's response to Donald Trump's peace efforts has been a clear escalation in Russian attacks.
But they don't only target the Ukrainian capital.
In the eastern Donbas region, more than 20 civilians were killed by a Russian glide bomb on Tuesday as they queued to collect their pensions.
Volodymyr Zelensky condemned the strike on the village of Yarova as savage and called once again on Ukraine's allies to increase the pressure on Moscow through sanctions.
His office said some US and European weapons components are still reaching Russia, including for the Iskander missile. Moscow has already substituted the rest with its own production.
Strong actions are needed to make Russia stop bringing death, Ukraine's president wrote.
Our team was filming on Sunday morning during the air raid on central Kyiv and captured the moment the cabinet of ministers was hit. The images appear to show a direct strike: a missile suddenly arcs downwards, right before the explosion.
There is no indication of it being intercepted by air defences.
When we were allowed into the vast, Soviet-era building to see the damage, the smell of burning intensified as we climbed towards the top floor.
The roof and part of the walls in the damaged area have been blown apart and there's a gaping hole in the floor.
Environmental and humanitarian concerns are escalating as civilians increasingly bear the burden of these attacks.
In Yarova, the death toll among elder citizens highlights the tragedy of war, further emphasizing the urgency for international response to Russia's aggression.
