A Yemeni prison guard was killed Tuesday in a militant attack on a prison compound in the southern city of Aden, police said.

Unidentified gunmen attacked al-Mansoura central prison in Aden and hurled a hand grenade on the prison walls, the police said in a statement.

According to the statement, a number of the assailants were killed in ensuing clashes with prison guards.

“A prison guard was seriously injured in the clashes and succumbed to his wounds,” the statement said.

Police said security forces seized two vehicles used by the militants and arrested a driver of one of the cars.

No group has yet claimed responsibility for Tuesday’s attack, but Yemen has been under a brutal US-Saudi offensive since March 2014.
