Prime Minister Gordon Brown on Thursday praised Pakistan's efforts in tackling extremism and pledged more support for its counterterrorism endeavors.

"It's true the international community expects a lot from Pakistan," Brown said at a news conference following talks with Pakistani Prime Minister Yousuf Raza Gilani.

Pakistan is not alone in facing up to the terrorist threat, Brown said. "This is your fight, but it is also Britain's fight," he said.

Brown did not repeat his call earlier this week for Pakistan to do more in tracking down Osama bin Laden, saying Britain believes the militant leader is hiding in Pakistan.

Gilani told the media, however, that he does not believe bin Laden was in Pakistan.

Pakistan wants a better explanation of U.S. President Barack Obama's new Afghan war strategy, Gilani said.

"We are studying that new policy. We need more clarity on it," he said during the news conference.
