A Pentagon report said Friday that the growth of Al-Qaeda safe havens in Pakistan's tribal areas is "troubling" and warned it may take Pakistan several years to turn around the situation.  The report to Congress by the US Department of Defense said Pakistan increased its troop levels in the border areas by 30,000 last year, and made "significant and costly" efforts to eliminate safe havens. "It is troubling that despite these efforts, safe havens in the FATA have grown in recent years," the report said.  The Pentagon report noted that 700 Pakistanis have been killed in suicide attacks since July 2007.It said "Al-Qaeda and other violent extremists continue to hide out in the FATA, where they are able to recruit, train, and target US and western interests, including plots against Europe and the US homeland." Madrassas, or Islamic religious schools, "continue to promote jihad and martyrdom, and provide potential operatives for acts of violence in Afghanistan," it said.
