"Out of the 23 bodies retrieved, 22 of them have been identified and taken by the relatives. Only one unidentified body is still at the mortuary," said Mugenyi.

"There was a problem with the bridge. It was made of wood, which had rotten. When the truck stepped on it, it broke. The truck plunged in and people drowned," he said.

The police have accounted for only eight survivors of the accident who were rushed to various health centers for treatment.
