Meanwhile, over 50 people died and dozens were wounded in a livestock market in Lahesh province.
Another bombing in destroyed the headquarters of the Houthi political office in Al-Jaraf in the capital Sanaa.
The rebel group had seized control of the capital in January.
Since end-March, coalition aircraft led by Saudi Arabia, have been bombing Houthi positions across Yemen, to check their advance and restore the legitimate government of President Abdu Rabbu Mansour Hadi.
On Monday, coalition airstrikes had targeted the main headquarters of the General People’s Congress party, an ally of the Houthis, in Sanaa, along with the houses of several leaders of the party and the rebel movement.
The strikes coincided with the visit of Ismail Ould Cheikh Ahmed, the UN special envoy to Yemen, who was in the capital to mediate for a humanitarian truce. (IANS)
