Members of the U.S. House Foreign Affairs Committee said Wednesday that Russian President Vladimir Putin is committing genocide in Ukraine. Their comments came a day before they were scheduled to meet with the chief prosecutor of the International Criminal Court.

The ICC in March issued an international arrest warrant for Putin for war crimes, accusing him of personal responsibility for the abductions of children from Ukraine. However, it has not yet charged him with any other offenses committed by Russian forces since their invasion of Ukraine more than 18 months ago.

The committee’s chairman, Rep. Michael McCaul, a Texas Republican, told reporters during a visit to The Hague that Putin “tried to erase a culture, a people and a religion, and that is the definition of genocide.”
