Pakistani President Asif Ali Zardari and British Prime Minister Gordon Brown on Friday discussed a range of regional issues, including Afghanistan, local media reported. The two leaders, who last met in London in May, said after Friday's meeting that Britain and Pakistan would work more closely together to fight terrorism. Britain and its allies in Afghanistan called for full cooperation from Islamabad in controlling the Afghanistan-Pakistan border region. The London talks came the day after a suicide bomber killed 22 Pakistani border guards in an attack at a checkpoint in the Khyber Pass, on the border between western Afghanistan and northern Pakistan.
