The US Air Base at Manas International airport in Kyrgyzstan has been asked to close when the lease expires in 2014, Kyrgyzstan President Almazbek Atambayev revealed.
Agence France-Presse has quoted the president as saying: "Our country will honour all its international agreements, but we have warned the US embassy that they will have to close the base in 2014."
Atambayev has asked for the base closure due to fear of retaliatory strikes by a country hostile to the US.
The air base has been used to support operations in Afghanistan since 2001.
Kyrgyzstan is the only country in the world to host both US and Russian military bases.
