BENI, Congo (AP) — Rebels in eastern Congo ambushed a stalled civilian convoy that was under military escort Wednesday, killing five people and abducting dozens of hostages initially. About 20 people remained missing hours later, the army said.

The attack took place after the convoy had stopped to repair one of the vehicles, Capt. Jules Ngongo, spokesman for the Congolese army in Ituri province, told The Associated Press.

Initially the gunmen kidnapped 80 people but he said the army was able to soon rescue 60 of them.
