Boston (ECN) - Rescue workers continue to sift through the rubble of what is left of the Marriott hotel in Islamabad.

Al-Qaeda is being blamed on the bombing, as more and more bodies are pulled out.

The death toll as of the end of the weekend was at 53, with at least 266 injured.

The bomber blew up a lorry which had 600kg of explosives in it on Saturday evening.

Among those dead was the Czech Ambassador Ivo Zdarek.

Two Americans were killed as well, as they were from the U.S. Defense Department.

Hundreds of people were at the hotel on Saturday when the bombing went off.

The lorry rammed through the security gates, blowing up.
