The long-expected move effectively marks a new regional gain for Russia, which has ramped up its focus on Africa and backed military regimes in neighboring Mali and Burkina Faso.

Deputy Secretary of State Kurt Campbell accepted the call to remove troops in a meeting in Washington with the prime minister of the junta, Ali Mahaman Lamine Zeine, US officials told AFP on condition of anonymity.

They agreed that a US delegation would head within days to the capital Niamey to arrange an orderly withdrawal, the officials said. Nigerien state television earlier announced that the US officials would visit next week.

The State Department made no immediate public announcement and officials said no timeline was yet set to withdraw the troops.
