At least 13 people were killed and 38 others wounded when a wedding in a rebel-held Yemeni town was hit by an air strike, a medical source said Thursday.

The bombing targeted a house hosting a wedding celebration in Sanban, in Dhamar province, some 100 kilometres (60 miles) south of Sanaa, medics and witnesses said.

The medical source did not specify the source of the bombing, but a pro-government Saudi-led coalition in March launched an air campaign in support of President Abedrabbo Mansour Hadi against the Iran-backed Shiite Huthi rebels.
