Karachi, Pakistan (CNN) -- Clashes at Pakistan's largest and busiest airport left more than 20 people dead after militants armed with grenades stormed into a cargo area Sunday.
Violence erupted at Jinnah International Airport in Karachi around 11:30 p.m. Sunday and raged on for more than five hours as security forces fought off attackers, leaving some passengers trapped inside the airport.
Officials at Jinnah Hospital said the dead included eight members of airport security forces, two Pakistan International Airlines employees and one ranger.
All ten militants involved in the attack were killed, military spokesman Maj. Gen. Asim Bajwa said. Two of them detonated suicide vests, he said.
