SANAA, Aug. 10 (CGTN) -- A total of 50 people died and 77 were injured after Saudi-led coalition air strikes hit buses in Yemen's northern province of Saada, according to the International Committee of the Red Cross (ICRC) in Yemen.

The latest casualty figure is given by the head of delegation for the ICRC in Yemen Johannes Bruwer on Twitter. According to him, out of the total of 50 dead and 77 wounded, the ICRC hospital in Al Talh received 30 dead and 48 injured, of which the vast majority were children.

A Saudi-led coalition battling in Yemen said it carried out the attack.

In a statement carried by the official Saudi Press Agency, the coalition called the strike a "legitimate military action" in retaliation for a missile attack on the Saudi city of Jizan on Wednesday.

Saudi Arabia leads an Arab military coalition that has intervened in the Yemen war since 2015 to support the government of exiled President Abd-Rabbu Mansour Hadi.

More than 10,000 Yemenis, mostly civilians, have been killed in the war and about three million have been displaced in what the United Nations describes as the world's worst humanitarian crisis.
