The United Nations' Security Council has unanimously approved a resolution intended to strengthen the fight against terrorism.

The Russian-sponsored measure seeks to expand prosecution and extradition of terrorists around the world.

Russia announced the proposal after a string of terror attacks that inlcuded airline hijackings and a school hostage taking incident.

The original proposal called for a global blacklist of terror groups, but challenges from Islamic nations Pakistan and Algeria on the council prompted modifications.

The resolution approved 15 to zero Friday sets up a "working group" to study actions to be taken against terrorists and terror groups.
