The Saudi-led coalition in Yemen has admitted an airstrike that hit a school bus last month, killing dozens of civilians, was unjustified. <br />For more on this and other news around the world we turn to our Ro Aram…<br />Aram… it's rare for the coalition it own up to its wrongdoings….<br /><br /> That's right Mark… it comes after mounting international pressure, including from the coalition's own western allies, to limit the number of civilian casualties in the Yemeni civil war. <br /> Last month's attack on the school bus at a market in Saada province killed more than 50 people, most of the children. <br />The U.S.-backed alliance, at the time, said the airstrikes targeted missile launchers used to attack southern Saudi Arabia a day earlier, and accused the Houthis of using children as human shields.<br />But in a statement on Saturday, it admitted that it had made mistakes, saying it will hold anyone responsible for the mishap accountable. <br /> The coalition's Joint Incidents Assessment Team noted that it had received intelligence that the bus was carrying Houthi leaders and was therefore a legitimate military target, but admitted that the location of the strike had led to collateral damage.<br />It added that delays in executing the strike and receiving a no-strike order should be further investigated. <br />The coalition also expressed regret and condolences to the families of the victims, saying it would work with the Yemeni government to compensate them.<br />The U.S. welcomed the statement, but human rights groups are not convinced and have accused the alliance of deliberately targeting civilians.<br /> Human Rights Watch on Sunday called last month's school bus bombing an apparent war crime, urging countries to immediately stop selling weapons to Saudi Arabia. <br />The conflict between the coalition and Iranian-aligned Houthi rebels has been going on for three-and-a-half years now and has claimed the lives of more than 10-thousand people. <br />
