NEW YORK, April 19, 2018 (MENA) - The Arab coalition reiterated its call for the United Nations (UN) to transfer premises of its organisations in Yemen from the Houthi-held areas to sites under the legitimate Yemeni government's control. The Saudi mission to the UN sent a message on Thursday to UN Secretary-General Antonio Guterres and the Security Council, saying that the Houthi rebels are setting up ballestic missile launchers near sites of the UN organisations' offices in Yemen, a step that prevents the coalition from targeting the Houthis there. The legitimate Yemeni government has delivered a similar message to the UN, urging it to move its offices to areas under its control. Separately, more Houthi leaders were killed at Saada border fronts in the north of Yemen, in clashes with the national army, according to local military sources.
