Pakistani investigators on Monday said they had found new evidence of al-Qaeda’s involvement in the suicide truck bombing of Islamabad’s Marriott hotel. Intelligence officials also reported the arrest of up to five militants in connection with planning future attacks.

According to an intelligence official, two of the five arrested men “came with conclusive evidence of close links to al-Qaeda. Their connection to the militant group is beyond any doubt”. The two al-Qaeda militants were arrested in Gujranwala, a large industrial city in the central Punjab province, while the other three were arrested in Kharian, a military garrison town, also in the Punjab.
