Kabul, Aug 1 (IANS): Flights in Afghanistan's Kandahar airport were suspended on Sunday after rockets struck the nation's second main international airport, a local official confirmed.

"The initial information found Taliban militants fired three rockets at the Kandahar International Airport and two of them struck the runway late Saturday night," the official told Xinhua news agency.

"Local authorities were inspecting and trying to repair and reopen the runway as soon as possible," the official said, adding that there were no casualties.
