A Russian rocket strike on a Ukrainian train station has killed 25 people

A Russian rocket strike on a Ukrainian train station has killed 25 people, Ukraine says, on the day marking six months since Moscow's invasion began.

It 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.

Russia has so far made no comment.
