Pakistani army fought an all-night battle Monday with Taliban gunmen who besieged Karachi airport armed with rocket launchers and suicide vests.

Twenty-eight people were killed during clashes, including ten militants officials said, as Pakistan's biggest city witnessed a return of the kind of spectacular offensive waged before by the Tehreek-e-Taliban Pakistan (TTP) during an insurgency that has claimed thousands of lives.

The attack at Karachi's Jinnah International Airport began just before midnight Sunday and around dawn, the military said that all 10 attackers had been killed.

Some of the gunmen were dressed in army uniform, as authorities put their mangled bodies, assault rifles, grenades and rocket launchers on display for the press. At least three attackers were suicide bombers.

But after authorities initially declared the airport cleared around dawn, an AFP reporter witnessed fresh gunfire break out inside the airport -- where explosions and fires had erupted during the night -- prompting security forces to relaunch the operation.

"The attack is over and we have cleared the area of all militants," a spokesman for the paramilitary Rangers, Sibtain Rizvi, told reporters later after nearly 12 hours of fighting in all.

The bodies of the 18 victims of the Taliban assault -- including eight airport security guards and four workers from Pakistan International Airlines (PIA) -- were taken to a Karachi hospital where another 26 wounded people were being treated, a hospital official said.
