A Yemeni military official says clashes in a southern province have left three suspected al-Qaida militants and two soldiers dead.

The official said gunmen attacked early Monday a military checkpoint in Sayoun, a city in Hadramawt province.

Another four militants and one soldier were wounded, he said on condition of anonymity according to regulations.

Meanwhile, the Defense Ministry said in a statement that unknown gunmen shot and killed an army officer and his son in a drive-by attack on his car in Hadramawt on Sunday.

It said two attackers on a motorcycle fired at Colonel Ahmed al-Merfidi who was driving his car with his son Yasser, killing them both.

The government ordered Sunday banning the movement of motorcycles in Sanaa.
