Airstrikes killed 36 suspected al-Qaida militants in southern Yemen on Thursday, as the government pressed on with a campaign to drive out fighters who have overrun several towns. A first round of airstrikes early today killed 30 militants near Zinjibar, one of the towns outside the government's control. The officials said, another airstrike later killed six militants in the nearby Arkoub area. Eight Yemeni soldiers were also killed in ground fighting near Zinjibar.
