Mounting pressure on Pakistan, British Prime Minister Gordon Brown today said its security forces must do more to break al-Qaeda and find Osama bin Laden. He told the BBC that eight years after the 2001 attacks on the US, nobody had been able to spot or detain or get close to the al-Qaeda leader. Mr. Brown said, Pakistan's security services must join the major effort to isolate the terrorist group. He said more progress is needed in taking out Osama Bin Laden and his number two Ayman Zawahiri. Mr. Brown said he will be talking to Pakistan's leaders and convey to them that if the international community is putting so much effort into building up Afghanistan to control its own affairs then Pakistan has got to be able to show that it can take on al-Qaeda. <br/><br/>Pakistan Prime Minister Yousuf Raza Gilani is due to meet Brown in 10, Downing Street next week.
