Brussels - The North Atlantic Treaty Organization on Sunday condemned the bomb attack that killed more than 50 people in a hotel in Islamabad, calling the act "grotesque."

Speaking for the military alliance, NATO General Secretary Jaap de Hoop Scheffer said: "I condemn in the strongest possible terms the terrorist bombing of the Marriott Hotel in Islamabad."

"This grotesque attack, which has caused huge loss of life and great suffering, has no justification whatsoever," he said, adding that NATO remains committed to working with Pakistan, including the new government, to combat the shared threat of violent extremism." (dpa)
