Airstrikes by the Saudi-led coalition targeting Shiite rebels have killed at least 15 people all members of one family in Yemen’s capital, Sanaa, officials said on Monday.

Security and medical officials, who remain neutral in a conflict that has splintered the country, said the airstrikes hit a building in the Sanaa neighborhood of al-Hasba, destroying it and also damaging nearby buildings.

The house that was hit stood next door to a rebel-controlled building, which appeared to be the intended targeted, they said.

Yemen has been torn by a ferocious war pitting the Shiite rebels known as Houthis and forces loyal to a former president against fighters who support exiled President Abed Rabbo Mansour Hadi, as well as southern separatists, local militias and Sunni extremists.

The conflict escalated in March when the Saudi-led, US-backed coalition launched an air campaign against the Houthis and their allies.

The war has so far killed over 2,100 civilians, according to the United Nations.

Meanwhile in Taiz, the country’s third largest city, rebel mortar rounds hit several homes and a market downtown, killing seven civilians and wounding at least 18, as ground fighting between the two camps raged on.
