The Czech foreign ministry will summon Russia's ambassador over Russian attacks on the Ukrainian village of Hroza this month, the Czech CTK news agency reports.
What happened during the attack?
On 5 October, a Russian rocket blast turned a cafe and store in the village in eastern Ukraine to rubble, killing 55 people.
About 60 people, including children, were attending a wake at the cafe when the missile hit, officials said.
Volodymyr Zelenskyy called the strike a "demonstrably brutal Russian crime" and "a completely deliberate act of terrorism".
