On Wednesday (24 August) Ukraine marked the 31st anniversary of its independence. The day also marked the end of the sixth month of the war, launched by Russia on 24 February.
The Russians decided to mark the day with rocket strike on a Ukrainian train station that killed 22 people.
Ukraine says five of the victims of the attack in the eastern town of Chaplyne burnt to death in a vehicle. An 11-year-old boy was also killed.
President Volodymyr Zelensky announced the strike in the middle of a UN Security Council meeting. He said about 50 people were injured.
Mr Zelensky said he learned of the strike on Chaplyne, in the Dnipropetrovsk region, as he was preparing to speak to the Security Council, adding: "This is how Russia prepared for the UN Security council meeting."
"Four passenger carriages are on fire now... the number of fatalities could increase," he continued.
This was not the first time that Russia targeted civilian train stations. In April, 50 people died in a similar attack.
In Ukraine, celebrations of independence day were subdued and the government had previously warned the Russians may use the occasion for a large scale provocation. However, around the world, there were gatherings of supporters in the streets to mark Ukraine's independence and world leaders also rallied to support the embattled nation to mark the occasion, with many countries announcing further assistance. A large rally in support of Ukraine was held in the Georgian capital, Tbilisi.
