US General David Petraeus is in Pakistan as part of his first trip as head of US Central Command.

The visit comes amid mounting tensions over US drone attacks in the country's tribal belt and an increase in attacks by al-Qaeda and Taliban-linked fighters.

The US presidential candidates are divided on how to tackle fighters along the Afghan-Pakistan border.

Kamal Hyder, reporting from North Waziristan, asks ordinary Pakistanis how they think the election of a new US president could impact on their lives.
