ISLAMABAD (AFP) - More than 300,000 people in northwest Pakistan have been displaced over the last six months because of fighting between Taliban insurgents and government troops, officials said Wednesday. A total of 55,729 displaced families, or 337,772 individuals, have been registered by the authorities, Shaukat Tahir, a senior official from the National Disaster Management Authority, told a news conference in Islamabad. Another official said the number displaced was for the time period since August. The military has launched major operations in Bajaur, Swat and other areas in the country's semi-autonomous tribal zones along the border with Afghanistan, where both Al-Qaeda and Taliban are said to have bases. Around 70 percent of the internally displaced persons (IDPs) were from the FATA, Tahir said, stressing that people were now beginning to return. He said people had left their homes because of an "ongoing operation in tribal areas". They were now returning "because roads have mostly been reopened and the military authorities have cleared the mines," he said. In an attempt to quell the bloody insurgency in the Swat valley, the govt on Monday signed an agreement with a pro-Taliban cleric to implement Sharia law in Swat. That should mean others will return home too, Tahir said. Amnesty International has estimated that 200,000-500,000 people have been displaced from the Swat valley over the past year. However, Tahir put the number for the past six months at 2,085 people. "International agencies threw around controversial figures about IDPs which were picked up by the media. Our figures are documented and came after a proper registration mechanism which can be verified," he said. In terms of aid, some 67,756 individuals were provided with shelter in 12 camps in NWFP, while 269,836 individuals were moved elsewhere, Tahir said. Nine emergency camps were set up in Swat alone, he added. Tahir said 13 UN aid agencies, the International Committee of Red Cross and the Pakistani Red Crescent were participating in relief efforts.In addition to Pakistani offensives, suspected US missile strikes are believed to have killed more than 300 people in the northwest since August 2008.
