Pakistan's defense minister says if the United States cuts off 800 million-dollar in military aid, the government may recall troops fighting militants in the restive tribal areas along the border with Afghanistan. Talking to media in Islamabad today, Mr. Ahmed Mukhtar said Pakistan cannot afford to keep its soldiers out in the mountains for such a long period. On Sunday the White House said that about a third of the 2.7 billion-dollar in annual U.S. military assistance to Pakistan will be withheld.
