Prime Minister Boris Johnson has promised the UK will respond with a "massive" package of sanctions over what he called a "hideous and barbaric venture" in Ukraine.

The Ukrainian Premier League season has been suspended following the attack.

In a brief statement, the league said the suspension was due to Ukrainian president Volodymyr Zelenskyy's decision to impose martial law but did not give any planned date to resume.
