Nearly 2,000 Yemeni inmates have revolted at a prison in the capital, taken a dozen guards hostage and called on President Ali Abdullah Saleh to step down.
The unrest broke out in the Sana’a prison late on Monday when prisoners set their mattresses ablaze and occupied the facility’s courtyard, AP quoted a security official said on Tuesday.
He said the guards fired tear gas and gunshots into the air but were not able to force the prisoners to give in.
The official said that additional troops have stationed to tighten security outside the prison.
He also said a number of inmates were hurt in the unrest.
Yemen has witnessed weeks of protests against President Saleh, who has vowed not to leave office until the end of his term in 2013.
