Biden: Putin committed war crimes

US President Joe Biden said on Friday that Russian President Vladimir Putin has clearly committed war crimes and the International Criminal Court's (ICC) decision to issue an arrest warrant for him was justified.

The ICC earlier on Friday called for Putin's arrest on suspicion of unlawful deportation of children and unlawful transfer of people from Ukraine to Russia since Moscow's invasion began of its neighbor last year. The United States is not a member of the ICC.

"He's clearly committed war crimes," Biden told reporters, referring to Putin.

"Well, I think it's justified," Biden added, referring to the warrant. "But the question is - it's not recognized internationally by us either. But I think it makes a very strong point."

The United States separately has concluded that Russian forces have committed war crimes in Ukraine and supports accountability for perpetrators of war crimes, a State Department spokesperson said in an emailed statement.
