UN warns thousands trapped in Yemen's northern flashpoint

CAIRO (AP) — A U.N. humanitarian agency warned on Tuesday that thousands of Yemeni civilians caught in fierce clashes between warring factions are trapped in an embattled northern district, an area that has become another flashpoint in the country's bitter civil war.

The number of displaced in the impoverished district of Hajjah has doubled over the past six months, with over 5,300 families fleeing from the district and its surrounding area in the past weeks, according to the U.N. Office for the Coordination of Humanitarian Affairs, or OCHA.
