At least 20 people have been killed in an airstrike which hit a bus carrying children in northern Yemen.
The International Committee of the Red Cross tweeted that an ICRC-supported hospital received dozens of dead and wounded after the strike on a market in Dahyan, Saada.
The attack has been blamed on the Saudi-led coalition waging war against Yemen’s Shia rebels
In the Yemeni capital, rebel-run Al Masirah TV gave a different number, saying the attack killed 39 people and wounded 51, mainly children.
The ICRC said in its tweet: “Under international humanitarian law, civilians must be protected during conflict.”
The Saudi-led coalition intervened in 2015 to try to restore the internationally recognised government to power after it was driven out of the capital by rebels.
So far, nearly 10,000 people have died in the war, which has unleashed what the United Nations describes as the world’s worst humanitarian crisis.
