At least 29 children have been killed and 30 wounded in a Saudi-led coalition air strike in Yemen, the International Committee of the Red Cross says.

The children, all of them under the age of 15, were travelling on a bus that was hit at a market in Dahyan, in the northern province of Saada.

The coalition, which is backing Yemen’s government in a war with the Houthis, said its actions were “legitimate”.

It insists it never deliberately targets civilians, but human rights groups have accused it of bombing markets, schools, hospitals and residential areas.

Yemen has been devastated by a conflict that escalated in early 2015, when the Houthis seized control of much of the west of the country and forced President Abdrabbuh Mansour Hadi to flee abroad.

Almost 10 000 people – two-thirds of them civilians – have been killed and 55 000 others injured in the fighting, according to the United Nations.
