An Emirati plane landed in Aden at dawn on Friday, bringing humanitarian aid to the southern Yemeni city only hours after its airport came under rocket fire from rebels.
The aircraft is the third to land in the port city since the symbolic reopening of the airport on Wednesday, after nearly four months of fierce fighting.
It delivered medical supplies from the Red Cross and United Arab Emirates before departing, an airport official said.
A vital supply artery for war-torn south Yemen, the facility came under fire from the Shiite Huthi rebels on Thursday as a Saudi plane was unloading humanitarian aid on the tarmac.
Overnight, rocket attacks on Aden killed three people and wounded 57, according to Al-Khader Laswar, a health official in the city.
The rockets were fired from north Aden, where the Huthi rebels still have a presence after being driven out of most of the city by fighters loyal to exiled President Abedrabbo Mansour Hadi.
The Saudi-led military coalition that backs Hadi carried out air strikes on Huthi positions in the area during the night, said a tribal source.
Elsewhere, coalition warplanes struck rebel positions in Omran, north of the rebel-held capital Sanaa, and Dhamar in central Yemen, according to residents.
