Ugandan and American troops have suspended their joint hunt for war crimes suspect Joseph Kony and his Lord's Resistance Army, delivering a major setback to efforts to capture a notorious warlord accused of abducting tens of thousands of children.

The Ugandan military and the U.S. State Department separately announced Wednesday that they had temporarily halted the search because of political turmoil in the Central African Republic, where Kony and his deputies are thought to be hiding.

Rebel groups unaffiliated with Kony seized power in the Central African Republic last week, forcing President Francois Bozize — who had been friendly with Washington — to flee the country.
