The US State Department has issued annual report of war on terror which revealed that 11,500 terrorism incidents occurred in Pakistan during 2010. Majority of these incidents occurred in the tribal areas as most of the terrorist outfits use the tribal areas as their bases to launch terrorist activities. Heavy casualties were recorded in different cities in the acts of terrorism. Suicide bombers were recruited as Khyber Pakhtunkhwa and FATA remained hub for the terrorist organisations, the report said. Pakistan's Frontier Corps and military initiated large-scale counterinsurgency operations in Mohmand, Khyber Pakhtunkhwa, and Orakzai, and added one battalion in Khyber Pakhtunkhwa, the rpeort said. When Pakistan conducted operations to eliminate safe havens in the country, it often lacked the capability to ensure these areas remained under the control of Pakistan's security agencies. Given its inability to pursue the complete elimination of the terrorist presence and fully eliminate terrorist safe havens, Pakistan utilized a strategy to conduct limited operations to "contain" terrorist operatives in known areas of activity, the report said. Pakistan's civilian government and military departments cooperated and collaborated with U.S. efforts to identify and counter terrorist activity in Pakistan, and the United States continued to engage Pakistan to ensure it had the will and capacity to confront all extremist elements within its borders. According to the report, the devastated floods in 2010 affected Pakistan very badly. However, the US State Department lauded the efforts of Pakistan armed forces in war against terror The U.S. government says Al-Qaeda remains the "most pre-eminent terrorist threat" to the United States -- especially because of the group's "cooperation" with Islamic militants in Afghanistan and Pakistan. In its annual report on global terrorism, the U.S. State Department said that although Al-Qaeda's "core" membership in Pakistan has become weaker, the group retains "the capability to conduct regional and transnational" terrorist attacks. The report said "increased resource-sharing" between Al-Qaeda and its Pakistan-based allies such as Tehrik-e Taliban Pakistan and the Haqqani Network means that the terrorist threat in South Asia remains high. The report covers 2010, before U.S. forces killed Al-Qaeda leader Osama bin Laden in Pakistan in May. Several outlawed Pakistan-based terror groups remain active in Kashmir and continue to target and plan attacks on India, the report said. Prominent among these terrorist groups are Lashkar-e-Taiba (LeT), Jaish-e-Mohammed (JeM) and Harkat ul-Mujahideen (HuM), which are having hundreds of armed supporters in Kashmir. LeT, designated as a Foreign Terrorist Organisation in 2001, is one of the largest and most proficient of the traditionally Kashmir-focused militant groups. "It has the ability to severely disrupt already delicate regional relation," said the State Department in its annual report on terrorism. The actual size of LeT is unknown, but it has several thousand members in Pakistan occupied Kashmir, Pakistan's Punjab Pakistan and in India's southern Jammu, Kashmir, and Doda regions. "Most LeT members are Pakistanis or Afghans and/or veterans of the Afghan wars. The group uses assault rifles, light and heavy machine guns, mortars, explosives, and rocket-propelled grenades," the State Department said. LeT maintains a number of facilities, including training camps, schools, and medical clinics in Pakistan. It has global connections and a strong operational network throughout South Asia, the State Department said. Pakistan continued to cooperate in regional and international counterterrorism forums. However, India-Pakistan counterterrorism cooperation was lacking in 2010, the report said.
