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.

A British Sky Broadcasting Group (BSkyB) logo is seen at the company's UK headquarters in west London July 25, 2014. Britain's BSkyB has agreed to pay 4.9 billion pounds ($8.3 billion) in cash to buy Rupert Murdoch's pay-TV assets in Germany and Italy, responding to slowing growth at home by creating a European media powerhouse. BSkyB, in which Murdoch's 21st Century Fox is also the top shareholder, will pay for the deal using cash, debt and a placing of shares that represents around 10 percent of its issued share capital. BSkyB said it would pay 2.45 billion pounds for Sky Italia and 2.9 billion pounds for Fox's 57 percent stake in Sky Deutschland to create a group with nearly 20 million customers.
