The attack apparently began at around 4:30 am, Kabul time, with a small vegetable truck trying to breach the perimeter of the airport compound. Inside was a bomb. Police reportedly blew up the truck:

Seven Taliban insurgents then took up positions in two buildings at the perimeter of the airport and began firing RPGS into the NATO/American held area in the airport. Kabul police reported at least some of insurgents were wearing Afghan police uniforms to help facilitate the attack.

Reporters racing to scene:
