Valerie Bony, 48, a BBC journalist, poses for a photograph in Abidjan, Ivory Coast, March 5, 2016. Women have long played a dominant role in agriculture in Ivory Coast and in the sprawling markets where most Ivorians purchase their daily necessities. Now some are breaking through into the most important positions in government, administration and business - positions long held by males in this traditional society. In 2012, Niale Kaba became finance minister, the first woman to hold the post in more than half a century as an independent nation. Ivorian women today work in a range of jobs – from gas-station attendant to plastic recycler and lawyer. International Women's Day is marked on March 8.

A BBC broadcast room is seen in a former Regional Government HQ Nuclear bunker built by the British government during the Cold War which has come up for sale in Ballymena, Northern Ireland on February 4, 2016. It is owned by the Office of Northern Ireland's First Minister and Deputy First Minister and capable of accommodating 236 personnel for extended periods. A large range of the original fixtures and fittings are to be included in the sale. It is believed to be one of the most technically advanced bunkers built in the UK with an array of advanced life support systems. In the event of a nuclear attack, the building could operate in a shut-down capacity for 30 days. The lower floor is completely underground and the upper floor is mounded over with 1 cubic metre of earth. REUTERS/Clodagh Kilcoyne
