The parliament in Kyrgyzstan has voted to close an air base key to US efforts in Afghanistan, as Washington urges Nato to send more troops to the war-torn country.

The closure of the Manas US airbase will make it increasingly difficult for soldiers and supplies to reach Afghanistan.

The base was expected to be used heavily as a build-up of US reinforcements into Afghanistan develops.
