Premise: The Pakistani news source GEO states that the first explosion occurred at 9:05 local time (0505 UTC), with the second explosion occurring minutes afterwards. The explosions occurred at the parking lot of the Marriott Hotel in Karachi, about 60 feet (18 meters) from the consulate gate. Damage to the building as well as over ten nearby vehicles was also reported. The Associated Press reports that the same consulate has been targeted twice in the recent past: an attack in 2002 left 14 Pakistanis dead, and in 2004 police defused a time bomb before it was set to detonate.
Hypothesis: A suicide bomber set off the first explosion at 9:05 local time.
