Violence escalates in Yemeni capital

Government forces clashed with opposition groups and explosions rocked Yemen\'s capital of Sanaa Monday, witnesses said. Rocket, mortar and heavy machine-gun fire was reported. The military has been fighting forces loyal to Gen. Ali Mohsin al-Ahmar, the rebel commander who joined anti-regime protesters earlier this year, Gulf News reported. Tens of thousands of protesters marched in Sanaa last week, calling for a U.N. resolution supporting a change in government.
