President Bush used his weekly radio address Saturday to highlight Pakistan's efforts to combat Islamist militants.

Mr. Bush cited a recent report released by his administration that says al-Qaida has established a safe haven in the tribal areas of Pakistan bordering Afghanistan.

He said Pakistani President Pervez Musharraf agreed to give tribal leaders more responsibility for policing their areas, but their efforts were unsuccessful.  Last Sunday, pro-Taleban militants broke the agreement.

Mr. Bush said the Pakistani president is taking active steps to go after radicals.  He noted Mr. Musharraf's decision to send Pakistani troops to raid an extremist Mosque in Islamabad.

That raid has triggered a wave of militant attacks across the country that has killed more than 160 people.

Mr. Bush's remarks were taped before the president underwent a medical procedure requiring him to temporarily hand over power to Vice President Dick Cheney.
