The United Arab Emirates and Oman plan to grant Yemen millions of crude oil to help the country face the acute fuel crisis coinciding with persistent unrest.

An official said on Tuesday, cited by Al-Oula newspaper, that the UAE will start in the coming days sending shipments within a three-million barrels of crude oil grant.

The official, who asked not to be named, said that the UAE will also grant Yemen 500000 tonnes of wheat as warnings of a food crisis emerged in the past few days due to acute shortages and associated price hikes.

Sources at the Aden Refinery confirmed that the UAE and Oman have decided to grant Yemen crude oil to enable it to cope with the current crisis after Saudi Arabia which granted Yemen last month three millions of crude oil.

"But the two Gulf countries did not inform the refinery when they will start sending their grants," the official said.

The first shipment of the Saudi donation arrived in Aden almost two weeks ago and the Aden Refinery is now processing it.

On Monday, Yemen received 30000 more barrels of Saudi crude oil as the crisis continued, with thousands of cars parked on main streets near filling stations in various cities.

Most recently, violence has been reported with several reported dead and tens injured at queues at stations.
