Meanwhile, some RPF soldiers remained as a decoy to carry out small-scale attacks on the Rwandan Army, who remained unaware of the Front's relocation. The reorientation towards guerrilla warfare began with a raid on a Rwandan customs post across the border from Katuna. Following the attack, the Rwandan Government accused Uganda of deliberately sheltering the RPF. The RPF's new tactics inflicted heavy casualties on the Rwandan Army, which reacted by shelling Ugandan territory. Ugandan civilians were killed and a significant amount of damage to property was incurred, and there were reports of Rwandan troops crossing the border to loot and abduct locals.
