Security officials say five Yemeni prisoners have been killed in clashes after riots in a prison south of the capital as some tried to flee.
The officials said the riots broke out Wednesday in the prison in the southern province of Dhamar, 60 miles (100 kilometers) south of Sanaa. The officials said some prisoners got guns, and clashes with the security followed as some tried to escape.
The officials, speaking on condition of anonymity because they were not authorized to speak to reporters, said 18 prisoners were wounded. Prison security officers used tear gas and fired at the prisoners to stop them from escaping.
Prisoners in Dhamar attempted an escape in December after rioting to demand better treatment. No one managed to escape in either incident.
