Paramilitary soldiers arrive at Jinnah International Airport in Karachi June 9, 2014.

Tehreek-e-Taliban militants, who launched a major assault on Pakistan's largest airport, were carrying XStat devices which can heal gunshot wounds within seconds and were aiming for a long siege of the facility, a security official said today."This devices are used to stop bleeding and heal gunshot wounds in 15 to 20 seconds," a source in the paramilitary rangers told PTI.The security forces found XStat or Faxziat devices from the bags of these terrorists who are said to be of Uzbek-origin."Clearly they came with a long siege of the airport in mind," he added.

The device, normally used by military medics and emergency services, is an applicator filled with dozens of tiny sponges that soak up a ton of blood when injected into an open wound.At least 28 people, including 10 terrorists, were killed in the attack before security forces eventually regained control over the key facility.
