According to the source, the bombing affected the Isa area of Al Hodeidah.
The source added that the coalition had also launched an airstrike in the province of Al Bayda, leaving two children killed, as well as bombed the northern province of Saada, located on the border with Saudi Arabia and considered to be a stronghold of the Houthi movement.

The strike comes after one-week UN-mediated talks on Yemen crisis settlement finished earlier in December. The sides agreed on a governorate-wide ceasefire and withdrawal of forces in Al Hodeidah, the establishment of a UN-chaired committee to monitor the process, a prisoner exchange, and humanitarian corridors to the city of Taiz.
Iran, in turn, responded to the allegations on Saturday, once again stressing that Tehran never provided weapons to the Houthi movement in Yemen.
Yemen has been engulfed in an armed conflict between the government forces led by President Abd Rabbuh Mansour Hadi and the Houthi rebels for several years. The Saudi-led coalition has been carrying out airstrikes against the Houthis at Hadi's request since March 2015.
