The World Food Programme welcomed a $18.6 million (Dh68.3 million) donation from the King Salman Humanitarian Aid and Relief Centre (KSRelief).
The contribution will provide Yemeni civilians and Rohingya refugees and their host communities with urgent food assistance.
For the next three months nearly 50,000 Yemenis will be provided with food assistance worth $17.6 million, while the remaining $1 million will go towards supplying food to some 28,000 Rohingya refugees.
More than 880,000 Rohingya refugees live in camps in the Cox's Bazar area, one of the poorest districts of Bangladesh, and are in need of urgent assistance.
"We are quite satisfied with the ongoing partnership with WFP, and this agreement will support the urgent humanitarian needs of the Rohingya refugees in Cox’s Bazar camps in Bangladesh," said Dr Abdullah Al Rabeeah, Advisor to Saudi Arabia's Royal Court and Supervisor General of KSRelief.
"The second agreement comes as part of the centre’s cooperation with WFP to provide immediate, comprehensive and sustainable support to avert famine in Yemen."
Meanwhile the Yemeni military on Friday morning carried out a new offensive against Houthi fighters near the areas of Al Jarrahi and Zubaid, on the Red Sea coast. The rebel militia suffered heavy losses. The ground operation was carried out under Arab coalition air cover.
According to WAM, the state news agency, sources on the ground have reported a rapid collapse in the Houthi ranks, with fighters abandoning their weapons and fleeing the frontlines.
Houthi leader Taha Mohammed Abdul Rahman Al Shahari and 38 of his companions were killed in clashes with the Yemeni military in the Hayes Front and the Tuhayat District south of Hodeidah Governorate, WAM also reported on Friday. In an undeclared state of emergency, it said, rebel members in the city of Hodeidah have called for blood donations to help save the wounded.
