Acting under Chapter VI of the United Nations Charter, the resolution unequivocally condemned all acts of worldwide terrorism as criminal and unjustifiable regardless of the circumstances in which the acts were committed.[4] All countries were called upon to implement international anti-terrorist conventions to which they were party to; states that had not adopted such measures were urged to do so immediately. The Council stressed that the United Nations played a vital role in strengthening international co-operation in the fight against terrorism.
