Sanaa- Asharq Al-Awsat

The Coalition for the Support of Legitimacy in Yemen said Wednesday that it targeted an unmanned aerial vehicle before its execution of an imminent terrorist attack.

The Coalition said in a statement that it "destroyed” the aircraft’s base at Sanaa international airport.

It said the attack comes in line with international humanitarian law.

The Saudi-led Coalition urged on Wednesday an intervention by the United Nations to save a hard-won truce in the battleground Yemeni city of Hodeidah from collapsing amidst persisting violations by Houthi insurgents.

The Coalition complained of repeated insurgency breaches since the truce went into effect.

"A total of 21 violations since ceasefire commencement have come to our notice," a coalition source told AFP on condition of anonymity.

"If the UN continues to drag the chain and take too long to get into the (military) theater, they will lose the opportunity altogether... and the agreement will turn a dead duck," the source said in English.

"We will continue to give them the benefit of the doubt and show restraint but early indicators are not promising."

Yemen's government, backed by the Coalition, has been at war with the Iran-aligned Houthi militias since 2015.

Oxfam warned on Wednesday that more than half a million displaced people in war-torn Yemen face the "double threat" of famine and freezing temperatures as winter sets in.

The aid group said some 530,000 displaced people are in mountainous areas, many living in makeshift shelters with no insulation or weatherproofing.

"Freezing temperatures could be the final straw for families already struggling to survive desperate hunger," said Muhsin Siddiquey, Oxfam's Yemen director.
