Norman Kember, 74, of Pinner, north-west London, James Loney and Harmeet Singh Sooden, were three of four men seized in Baghdad in November.
Mr Kember is said to be in a “reasonable condition” while the two Canadians were taken to hospital.
The body of murdered US citizen Tom Fox was found in Baghdad two weeks ago.
The men were carrying out work in Iraq as part of peace group Christian Peacemaker Teams.
They were abducted on 26 November.
