At least 24 Yemeni civilians were killed in an air raid Sunday on a market near the border with Saudi Arabia, a medical official said.

Most of the casualties worked in the Mashnaq market, which sells the mild narcotic qat, in the rebel-controlled northern Saada province, the official told AFP on condition of anonymity.

A Saudi-led coalition has been carrying out air strikes in Yemen for more than two years against Iran-backed Shia Houthi rebels.
