In Pakistan, the hostage crisis has ended with commandos storming a building near army headquarters in Rawalpindi this morning freeing 42 hostages and killing four attackers. One of the terrorists was arrested while fleeing. The heavily-armed terrorists were holed up for nearly 20 hours in the building after targeting Pakistan army headquarters.Chief military spokesman Major General Athar Abbas told state-run PTV that the operation is over. He said, the situation is under control and the entire area has been cleared. There are no terrorists inside the building. Major General Abbas said the commandos killed four terrorists, some of them wearing suicide jackets. The development came a day after a group of terrorists armed with assault rifles and grenades launched an attack on the army's General Headquarters in Rawalpindi and took several security personnel hostage. Power was cut off in the area where the terrorists were hiding since late last night. TV channels reported that some hostages were freed from one room after the commandos gunned down a suicide bomber before he could detonate his explosives.
