Theresa May will urge the Arab and EU states to "redouble our efforts" to reach a peace deal in Yemen, as the UK pledged a further £200m in humanitarian aid for the war-torn country.

The prime minister, speaking on her way to the EU-league of Arab states summit in Sharm el-Sheikh, said the "situation in Yemen cannot go on."

"There must be a political settlement - this is the only way to end this crisis and the suffering it's caused," she said.

The prime minister called on the international community to turn December's peace talks in Stockholm into a "lasting peace" and said the suffering must end.

The civil war between Saudi-backed forces and Houthi rebels has been raging for nearly four years and has brought humanitarian crisis to the Yemeni people, with millions on the brink of starvation.

Mrs May wants all sides to press on with peace talks which resumed late last year for the first time since 2016, with the two warring sides agreeing to a ceasefire in the port city of Hodeidah and pledging to withdraw troops.

She said: "Pressure must be brought to bear on all those involved on the conflict.
