Yemen's al-Masirah TV said on Tuesday that a busy restaurant adjacent to the al-Khamis market was also targeted in the airstrikes, Press TV reported.
Vendors from other places had gathered in the market to seek cover from the Saudi strikes.
Yemeni sources say Saudi jets also bombed several civilian targets in Ta’izz, Jawf and Sana’a provinces, but there was no immediate report on casualties.
In response to the Saudi aggression, Yemeni forces backed by allied Popular Committees loyal to the Houthi Ansarullah movement, killed a number of Saudi mercenaries in the city of al-Ghayl in Jawf province.
In addition, a Saudi mercenaries’ commander was killed in Ta’izz province.
Saudi Arabia started its aggression in Yemen March last year to supposedly bring former president and Riyadh’s ally, Abd Rabbuh Mansur Hadi, back to power.
At least 8,400 people, among them 2,236 children, have reportedly been killed and 16,015 others injured, since then.
Saudi airstrikes have also taken a heavy toll on the already impoverished country’s infrastructure, destroying many reservoirs, hospitals, schools, and factories.
