A bus plunged over a cliff Saturday in southern Saudi Arabia, killing at least 25 people on board, the state-run news agency reported.

The official Saudi Press Agency said 25 people were killed and eight were wounded, citing police Col. Abdulla al-Qurni in the southern district of Assir, where the crash took place.

But Okaz newspaper, which is deemed close to the government, reported that 26 people died and seven were wounded.

The bus, which started its journey from the capital Riyadh, drifted to the side of a mountain road, crashed through a guardrail and landed in a deep valley near the southwestern city of Abha, Okaz reported.

The Saudi reports did not provide the nationalities of the deceased, but the Egyptian daily Al Gomhuria reported that 7 Egyptians were among them.
