Yemen’s Houthi rebels fired on Saturday artillery around an oil refinery in Aden, starting a fire that poured black clouds over the city, and 14 people were killed in clashes between the Houthis and pro-government forces, witnesses in the city said.
Aden has been in the grips of fierce clashes between pro-government and Houthi militants. The port and the refinery in the city are controlled by forces loyal to exiled president Abd Rabbuh Mansur Hadi.
An official at the Aden Refinery told AFP that Houthis shelled a nearby port to prevent a Qatari vessel carrying food aid.
Residents in Aden complain of food and water shortages as humanitarian aid is hampered by the fighting.
Elsewhere in the country, Jawf, Sadaa, Taiz and Hodeida, witnessed air raids targeting Houthi posts.
Yemen’s Houthi militants seized the capital Sanaa in September, taking control of several major cities.
In March, a Saudi-led coalition began an extensive air campaign against the Houthi forces.
The rebel forces comprise both Houthis and troops loyal to former president Ali Abdullah Saleh, who was ousted in February 2012.
UN says at least 2,800 people have been killed in the fighting and 20 million people are in need of urgent humanitarian aid.
