Sanaa, Yemen: At least 15 people were killed and 38 others wounded in the bombing of a wedding in a rebel-held Yemeni town, a medical source said on 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 Iran-backed Shiite Huthi rebels.

The coalition has been accused of several deadly attacks that hit civilians.

Last week the coalition denied its warplanes bombed a wedding near the Red Sea city of Mokha, in which at least 131 people were killed.

The United Nations said that incident may have been the deadliest episode since March, when the Riyadh-based coalition launched its air war as the rebels advanced on the second city of Aden.

Hadi fled that month to Riyadh then returned to Aden in September, after loyalists backed by coalition forces retook the port city and four other southern provinces.

The United Nations says around 5,000 people have been killed and 25,000 wounded, many of them civilians, in Yemen over the past seven months.
