Yemen war escalates with no end in sight

Over the last weeks, separatists in the south have attacked and occupied government buildings and the UN envoy to the country has resigned after failing to bring the various factions together.

Almost three years of civil war in Yemen is forcing huge numbers of people from their homes. Activists say in the past few months alone, fighting in northwestern areas has displaced more than half a million people. And there are no signs of the war ending.
