Smoke billowed from the port city of Mocha, Yemen, after a Houthi attack that killed 11 people on Sunday.
It followed an earlier drone attack on a Saudi oil refinery on the coast of the Red Sea, escalating tensions as the long-standing truce between the group and the internationally-recognised government seemingly collapsed last month.
A further 32 people were wounded in the attacks, 6 of them civilians, according to AFP citing a medical source in Mocha.
