The International Criminal Court will investigate possible war crimes in Ukraine.
The top prosecutor at the International Criminal Court announced his intent to open an investigation just days after Russia launched its invasion.
He said in a statement that his office had received referrals from 39 nations that are part of the International Criminal Court.
The work in the collection of evidence has begun after Khan notified the Presidency of his decision to immediately proceed with active investigations.
Khan said the investigation would consider any past and present allegations of war crimes, crimes against humanity or genocide on any part of the territory of Ukraine.
Russia's invasion of Ukraine has been described as a "crime of aggression" by the human rights group.
The United States is not a member of the International Criminal Court. Lindsey Graham, a Republican from North Carolina, introduced a Senate resolution this week urging the court to investigate Russia's actions.
Graham, who threatened to cut off aid to Palestinians if they filed a claim against Israel at the International Criminal Court, said the international body made sense for prosecuting any offenses in Ukraine.
He said the court doesn't make sense when it comes to America or Israel.
The treaty Clinton signed in 2000 creating the International Criminal Court was never voted on by the Senate. George W. Bush withdrew from the agreement.
