Pakistan and Afghanistan said on Tuesday they had agreed their security forces would cooperate to fight terrorism and hunt down militants as well as to battle drugs. Speaking after talks in Islamabad, Afghan Foreign Minister Abdullah Abdullah said Afghanistan had decided to start releasing some of the hundreds of Pakistani supporters of the Taliban imprisoned after the fall of radical Muslim regime last year. He also said he had agreed with Pakistan's Interior Minister Moinuddin Haider to establish a mechanism for cooperation between the security organizations of both countries. He said terrorism had not been completely stamped out in Afghanistan, or the region, despite the destruction of al Qaeda bases in the country during the U.S.-led war on terror. "Of course the major part has been done, which is to destroy the bases in Afghanistan," he told reporters. "(But) the campaign should continue for some time. We all agree that terrorism is not eradicated or eliminated." Haider said it was in the interests of the people of the region that terrorism be stopped. "We have said it is in the common interests of this region that we must have join efforts through our security forces through cooperation between border forces and cooperation between anti-narcotics forces," he told reporters. "We have (told) them that we are ready to assist you in training anti-narcotics forces, police and other security forces so that we have joint operations and joint understanding." Abdullah, a key member of the Northern Alliance, which overthrew the radical Islamic Taliban regime with U.S. support last year, said the two sides had "very good and constructive talks" on security issues, prisoners, refugees and smuggling. Pakistan was a supporter of the Taliban but abandoned the group after September 11.
