Air strikes by the Saudi-led coalition fighting the Houthi group in Yemen killed 10 civilians in Hudaydah province on Saturday, medics and Houthi media said.
Medical sources told Reuters the civilians died when the air strikes hit a Houthi checkpoint in the town of Jabal Rass while a bus was passing through.
Eight members of the same family were among the victims, they said.
The Houthi movement’s Al Massira TV said 17 died and many others were in a critical condition.
A spokesman for the Saudi-led coalition could not immediately be reached for comment.
The coalition intervened in Yemen’s war in 2015 to restore the internationally-recognised government to power. It has conducted thousands of air strikes targeting the Iran-aligned Houthis, and has often hit civilians, but denies doing so intentionally.
The war has killed more than 10,000 people, displaced more than two million and driven the country – which was already the poorest on the Arabian Peninsula – to the verge of widespread famine.
