Around four people have been killed in what appears to be a terrorist attack in Pakistan. Blasts ripped through a parking lot behind the Marriott hotel near the US consulate in the city of Karachi, injuring nearly 50. They happened as people were arriving for their morning shifts.

Police believe suicide car bombers may have been responsible. Karachi is a hotbed of terrorist groups, including al-Qaeda. It has seen attacks on western targets in the past. It is reported that at least one US citizen who worked at the consulate is among the dead, and that another foreigner is missing. Speaking in India, President Bush said the incident would not deter him from pursuing his Asian tour to Pakistan. He is due to arrive in Islamabad on Saturday.
