Security fears over Khyber Pass

Gordon Brown and Pakistan's president Asif Ali Zardari have met in Downing Street to discuss the security situation at the border with Afghanistan.

President Zardari said that his country is doing all it can to hunt down the Taliban and control its border with Afghanistan.

But on Thursday a suicide bomber killed 22 police officers at a border crossing in the Khyber pass and there are fears the militants maybe regrouping.
