Ex-Ugandan rebel commander Dominic Ongwen has been convicted of war crimes at the International Criminal Court.
Ongwen, a feared commander of the Lord's Resistance Army (LRA), is the first member of the LRA to appear before the court.
He was convicted on 61 of the 70 counts of crimes against humanity and war crimes he faced.

The charges relate to attacks on four camps for internally displaced people in Uganda in 2004.
Ongwen's sentence is to be handed down at a later date. He could face life imprisonment.
This case presented a dilemma to the court as he appeared to be both the victim and the alleged perpetrator.
He said he was abducted by the LRA and forced to be a child soldier, before going on to rise up the ranks to become the deputy to LRA commander Joseph Kony.
But reading out his verdict, presiding judge Bertram Schmitt said: "His guilt has been established beyond any reasonable doubt.
"The chamber did not find evidence that supported the claim by the defence that Dominic Ongwen suffered from any mental disease or disorder during the period relevant to the charges, or that he committed these crimes under duress."
He was convicted of counts including war crimes, crimes against humanity, torture, sexual enslavement and pillaging.
The ICC issued a warrant for his arrest in 2005 and US and African forces had been searching for him since 2011.
In 2015 he gave himself up in the Central African Republic (CAR) and his three-and-a-half year trial in the Hague ended in March.
His lawyers had asked for his acquittal and are quoted by Reuters news agency as saying in the closing argument: "When Ongwen was abducted he had no option, he was made a slave. That slavery continued until he left the bush."
But prosecutors reportedly insisted he was an adult at the time of the alleged offences so cannot be excused of responsibility.
