Thirty people were killed in siege on Karachi airport.
The assault has left Pakistan`s nascent peace process with the Tehreek-e-Taliban Pakistan (TTP) in tatters and officials in the northwest reported that about 25,000 people had fled a restive tribal district in the past 48 hours, fearing a long-awaited ground offensive.
Ten militants were among the dead in the assault on Karachi`s Jinnah International Airport, the latest spectacular offensive to be launched by the TTP in an insurgency that has claimed thousands of lives since 2007.
Authorities were checking reports that seven airport workers were trapped in cold-storage facilities after apparently shutting themselves inside to escape the carnage.
"We are looking into this and according to the families some seven people were trapped inside the cold storage and were in contact with the families on cell phone," said Abid Qaimkhani, a spokesman for the Civil Aviation Authority.
