President Asif Ali Zardari of Pakistan and Iran's Mahmoud Ahmadinejad have inaugurated a controversial gas pipeline linking the two neighbours.

The US had warned that the project could incur sanctions connected with Iran's nuclear programme.

The long-delayed pipeline is seen in Pakistan as a way of alleviating the country's chronic energy shortages.
