ISLAMABAD (AFP) - The United Nations on Monday warned it may have to shut down aid projects in Pakistan, after receiving only a fifth of the funds requested in an appeal for more than half a billion dollars. The United Nations launched the 537-million-dollar appeal in February to feed and assist more than one million people displaced by conflict in Pakistans northwest and in border areas with Afghanistan. The response by the international community to this appeal is inadequate, UN humanitarian coordinator for Pakistan, Martin Mogwanja, told a news conference in Islamabad. Humanitarian actors responding to the needs of the people are concerned that some of the projects may have to be suspended because of lack of finances, he said. Mogwanja said that the United Nations had so far received only 106 million dollars from the donors, which was just 20 percent of the total appeal. He said the United Nations urgently needed the funding, with 1.3 million people still displaced in the northwest and the rugged tribal regions. Mogwanja stressed that displacement had not ended and there were more people on the move in the tribal regions of Orakzai and Kurram. The UN refugee agency said Friday that more than 35,000 families or around 210,000 individuals from Orakzai and Kurram fled the military operation and Taliban-linked violence since November. These people have been registered as internally displaced persons, mostly in the northwestern towns of Hangu and Kohat. Last year, a total of 3.1 million people were displaced from their homes in NWFP and the semi-autonomous FATA along the Afghan border. Nearly two million people have returned home, but uncertainty continues to exist in the wake of ongoing clashes between army troops and Taliban insurgents in most of the northwest and the tribal regions bordering Afghanistan.
