Gunmen in north-west Pakistan have attacked a convoy carrying supplies to Nato troops in Afghanistan.

Two armed men on a motorbike opened fire on vehicles as they headed towards a border crossing in Khyber region, officials said. A driver was killed.

It is the first such attack since Pakistan agreed to reopen routes three weeks ago after a seven-month blockade.

Pakistani officials were reacting to a US drone strike last November which killed 24 soldiers.

The Taliban oppose Pakistan's support for the US-led mission in Afghanistan.
