Yemen's Houthi rebels have backed the United Nations' call for an independent investigation into a Saudi-attack on a bus full of school children on Thursday.
The Houthis say at least 50 people were killed in the attack in Saada province, and over 70 were wounded.
The Saudi-led coalition insists it was striking at legitimate targets.
Al Jazeera's Mohammed Adow reports from Dijbouti.
