Lord’s Resistance Army commander Dominic Ongwen in ICC custody

A commander from a fearsome Ugandan rebel group known for abducting and torturing children was taken into custody early Wednesday at the International Criminal Court, where he faces charges including murder and enslavement, the U.S. Ambassador to the United Nations said.

Dominic Ongwen was flown out of Africa on Tuesday. His arrival in The Hague marks the first time a member of the Lord's Resistance Army, which is led by the notorious warlord Joseph Kony, has faced international justice.

Ongwen's transfer from the Central African Republic to The Hague, "is a welcome development in the international community's campaign to counter the LRA's dehumanizing violence, and to bring perpetrators to justice after more than two decades of the LRA's brutal campaign of torture, rape and murder," said Ambassador Samantha Power.

The court did not immediately confirm Ongwen's arrival at its detention center near the Dutch North Sea coast, two weeks after he surrendered in the Central African Republic. Ongwen will undergo medical tests and will likely make his first court appearance within days.

His extradition comes nearly a decade after authorities first charged him and four other Lord's Resistance Army top commanders. Three have since died and only top leader Kony remains at large.

Ongwen has been accused of atrocities against civilians in Uganda and in parts of Central African Republic, South Sudan and Congo. For more than a quarter of a century, the LRA has terrorized central Africa with a campaign of killings, torture, kidnappings, using child soldiers and sex slaves.

"The transfer of Dominic Ongwen to the ICC is a major step for those affected by the LRA's long history of crimes," said Daniel Bekele, Africa director at Human Rights Watch. "All eyes will now be on the ICC to deliver fair, meaningful justice that will resonate with the LRA's victims."

After years of hiding in the remote forests of central Africa, Ongwen said it was time to face the charges against him. He surrendered on Jan. 6 in the Central African Republic.

Ongwen's surrender is seen as a severe blow to Kony and the LRA, who are being hunted down by the Ugandan army with help from U.S. military advisers.

 "Today's developments give hope -- to the survivors, to the four countries affected by the LRA, and to their partners around the world -- that the nightmare of the LRA can be brought to an end," U.S. State Department spokesperson Jen Psaki said in a written statement. "We call on the remaining LRA members to follow the lead of the more than 250 individuals who have left the LRA since 2012 to put down their arms and return home."

U.N. Secretary-General Ban Ki-moon and the U.N. Security Council both issued statements welcoming Ongwen's transfer to the International Criminal Court.

Ban called it "a step forward in efforts to bring justice to the thousands of victims of LRA violence" in Uganda and other African countries over the past 28 years.
