Yemeni air force bombs al Qaeda-held city

The Yemeni air force bombed an al Qaeda-held southern city on Monday while residents in another city said soldiers had opened fire on a demonstration and run protesters over with bulldozers, killing at least 15. There were flashpoints across civil-war-threatened Yemen including six soldiers being killed in what appeared to be an ambush near Zinjibar, a coastal city taken over a few days ago by Islamist and al Qaeda militants.
Residents there said jet fighters later strafed militants with bombs but also hit buildings in the town of about 20,000. At least 13 have been killed in the bombing and artillery shelling, residents said. Global powers are worried Yemen, near financial collapse and home to al Qaeda militants, could turn into a failed state sitting along a vital sea lane for global oil supplies and adjacent to Saudi Arabia, the world's biggest oil exporter.
