About 2,000 inmates have staged a revolt at a prison in the capital of Yemen, taken a dozen guards hostage and joined calls by anti-government protesters for the country's president to step down, a Yemeni security official said.
He said the unrest in the Sanaa jail erupted late last night when prisoners set their mattresses ablaze and occupied the facility's courtyard.
He said the guards fired tear gas and gunshots into the air but could not subdue the inmates.
The official said today that troops have beefed up security outside the prison. He added that a number of inmates were hurt in the unrest.
Yemen has been rocked by weeks of protests against President Ali Abdullah Saleh.
