Once involved in peacekeeping efforts in war-hit countries, General Abdourahmane Tchiani has now triggered a major crisis in West Africa by staging a coup in Niger.

Low-profile and hitherto little known outside his immediate circle, he was the commander of Niger's presidential guard until he emerged from the shadows to overthrow the man he was charged with protecting, President Mohamed Bazoum.

Gen Tchiani declared himself the head of the National Council for the Safeguard of the Homeland, the military junta set up after he seized power on 26 July.

Meanwhile, his former boss languishes under house arrest. Mr Bazoum has been in sporadic telephone contact with international leaders but he is otherwise isolated.
