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, while Moscow has already substituted the remainder 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.
The missile - packed with more than 100kg (220lb) of explosives - did not detonate, limiting the damage to three floors. Ukrainian officials believe that the missile hitting the building is indicative of Russia's escalating military tactics, which have grown more frequent and widespread.
Closer to the front line, the tactics are different: deadly glide bombs arrive almost without warning. This week, elderly citizens, who are usually less able to evacuate, have suffered the most devastating impacts of these strikes.
Ukraine's leaders continue to call for more decisive action from the global community to address Russia's increasing aggression and protect their citizens from ongoing attacks.
