Karachi : Fresh gunfire has erupted at a Karachi airport just hours after a ferocious terrorist assault by suspected Islamist militants left at least 23 dead.
Pakistan's security forces have relaunched a military operation that ended the previous six-hour siege.
"We have relaunched the operation and called in additional troops," said Sibtain Rizvi, spokesman for the Rangers paramilitary force.
One police officer had been injured, he said.
An Agence France-Presse reporter at the scene said gunshots could be heard inside the airport and that rangers and elite commandos were rushing inside.
The initial assault at the Jinnah International Airport began late on Sunday and carried through into Monday morning, local time. Explosions and gunfire rang out across the airport as police and security forces battled with attackers, and passengers waited anxiously in a nearby terminal and in airplanes stranded on the tarmac. Just before 5am, after five hours of siege, the military reported that the last of 10 attackers had been killed.
