A car bomb ripped through a military kitchen in Aden used to prepare meals for Yemeni forces trained and backed by the United Arab Emirates (UAE), killing at least four people on Tuesday.
According to the witnesses, several people were wounded in the blast caused by a car laden with explosives, apparently driven by a suicide bomber, towards the kitchen in al-Derain area in northern Aden.
No one immediately claimed responsibility for the attack and officials could not be reached for comment, reports Reuters news agency.
It was the second attack of its kind targeting security forces in the city, where UAE forces from the Saudi-led coalition that has been operating in Yemen since 2015 hold sway.
Witnesses said rescuers were trying to pull out four charred bodies clearly visible in the destroyed kitchen. The force of the blast damaged stores and cars nearby.
The Saudi-led coalition joined the Yemen conflict in March 2015 after the armed Iran-aligned Houthi group pushed towards Aden, forcing the internationally-recognised President Abd-Rabbu Mansour Hadi into exile in Saudi Arabia.
Last month, UAE-backed southern Yemeni forces wrested control of Aden from forces loyal to Hadi in several days of fighting that ended with a truce brokered by Saudi Arabia and the UAE.
