A five-year-old boy in Ukraine has died in hospital days after his sister and parents were shot dead by Russian troops, according to reports.
The youngster, called Semyon, was travelling in a car with his family when it was attacked as they tried to flee Kyiv on Saturday.
A Russian sabotage and reconnaissance group opened fire on the vehicle, Kyiv’s deputy mayor said, killing Semyon’s 10-year-old sister Polina and parents, Anton Kudrin and Svetlana Zapadynskaya.

Amnesty International said Russia’s use of widely-banned cluster munitions on a pre-school in northeastern Ukraine “may constitute a war crime”.
Three people were killed, including a child, when the explosives hit the nursery and kindergarten in the town of Okhtyrka on Friday morning as locals took shelter inside, Amnesty said.
Amnesty said Russia’s invasion of Ukraine is a clear violation of the United Nations Charter and an act of aggression that is a crime under international law.
