Cameroonian soldiers have freed a German hostage kidnapped in Nigeria by the Islamist militant group Boko Haram.
Robert Nitsch Eberhard, a teacher, was abducted in July 2014 in Adamawa State by the group, Cameroon’s government said.
He was freed in a “special operation of the Cameroon armed forces and security services of friendly countries”.
Boko Haram has seized control of towns and villages in north-east Nigeria and launched raids into Cameroon.
It is not clear which countries contributed to the operation to free Mr Robert.
The former hostage arrived in Yaounde in the company of Ferdinand Ngoh Ngoh, a senior official in the presidency, the BBC’s Randy Joe Sa’ah reports from Cameroon’s capital.
They were received at the airport by several ministers and the German ambassador.
Officials would not say how he was released, except to mention their gratitude to the military, our reporter says.
