Yemen's Houthis shell Aden refinery for second time - official
"The refinery suffered today a new rocket which targeted an empty storage tank at the refinery port," Nasser Shayef, a media official at the Aden refinery told Reuters by telephone.
The militia has been locked in deadly street battles with local fighters for three months as Arab states bomb the Houthis and have imposed a near-blockade on the country which has cut off trade in food and fuel.
