A little-known group calling itself the Fedayeen Islam (Partisans of Islam) has claimed it planted the bomb that destroyed the Islamabad Marriott Hotel. An unverified report said the group communicated several demands to a television station in the Pakistani capital, including that Pakistan sever ties with the United States.
The Interior Ministry said the president, prime minister and chief of the army had been due to attend a dinner at the hotel on Saturday night when the attack killed 53 people, but they switched venue.
The Czech ambassador and at least three other foreigners were among those killed in the blast. 266 people were wounded.
