The suspected Congolese war criminal Bosco Ntaganda, also known as “The Terminator”, has handed himself in at the US embassy in Kigali.
Ntaganda is wanted by the ICC for conscripting child soldiers, rape, ethnic persecution and murder.
"I can confirm that Bosco Ntaganda... walked into the US embassy in Kigali this [Monday] morning," US state department spokeswoman Victoria Nuland told media.
"He specifically asked to be transferred to the ICC in The Hague."
The US, which does not recognise the ICC, is now in talks with the court and Kigali to "facilitate his request", Ms Nuland said.
Human rights groups have called on the US to transfer Ntaganda to The Hague.
According to AP, Sasha Lezhnev, senior analyst for the Enough Project in Washington said:
"Bosco Ntaganda is not called The Terminator for nothing. If he is at the US embassy, the US should immediately hand him over to the International Criminal Court for trial,
"This would send serious signals to current and future warlords who continue to perpetrate atrocities in eastern Congo.''
