Uganda's attorney general says the country has assured the International Criminal Court of "full cooperation" on the case of Dominic Ongwen, a Ugandan rebel commander who faces trial.

Peter Nyombi said Monday that Uganda's government would help with investigations as well as identifying witnesses. A team from The Hague is traveling to Uganda next week to consult with officials.

Ugandan President Yoweri Museveni has been critical of the international court. Nyombi said, however, that Uganda believes it's "more convenient for the ICC to try Ongwen."

The ICC has set Aug. 24 for a hearing to assess if evidence is strong enough to merit a full trial.

Ongwen faces charges of war crimes and crimes against humanity for his alleged role in the Lord's Resistance Army rebel group.
