(KARACHI, Pakistan) -- A group of militants attacked a Pakistani naval base in Karachi Sunday night, leaving at least 12 people dead, according to the BBC.
It is believed that 10 to 15 insurgents raided Pakistan Naval Station Mehran, igniting a firefight with Pakistani commandos. Explosions and small arms fire were heard for several hours as naval commandos worked through Monday morning to regain control of the base.
The militants damaged a P-3C Orion, a maritime surveillance plane that the U.S. gave to Pakistan in 2010, to the point that it likely cannot be fixed in Pakistan, according to a Pakistani Navy spokesman. Other military assets on base may have also been damaged or destroyed due to the heavy exchange of fire, according to a security official.
A handful of U.S. contractors who were assigned to the base for maintenance on a P-3C Orion were evacuated, a U.S. military spokesman said. U.S. personnel assigned to Pakistan's Navy for professional training in Karachi were also all accounted for, according to U.S. embassy spokesman Alberto Rodriguez.
The Pakistani Taliban has reportedly taken responsibility for the attack.
