Saudi Arabia's military has said that Saturday's airstrike struck a militia training camp but offered no evidence for its claims. A 14-member team set up by the coalition to investigate allegations of wrongdoing said it had opened an inquiry into reports that the school was hit and would make its findings public.
There was no immediate comment from Saudi Arabia on Monday's airstrike, which was at least the fourth on a Doctors Without Borders-supported medical facility in Yemen since the war began in early 2015. Last year, one person was killed in an airstrike on a health center in Saada province, and a mobile clinic in the southern province of Taiz was also hit, according to the aid agency. In January, another hospital in Saada was targeted, killing six.
Several organizations working in Yemen condemned Monday's attack and called for an independent investigation.
"This was a horrific attack killing sick and injured people and the medical staff desperately trying to help them," said Sajjad Mohammad Sajid, Oxfam's country director in Yemen. "The world cannot continue to turn a blind eye as the most vulnerable suffer in this terrible conflict."
"Today's air strike appears to be the latest in a string of unlawful attacks targeting hospitals highlighting an alarming pattern of disregard for civilian life," Magdalena Mughrabi, Amnesty International's deputy director of the Middle East and North Africa Program, said in a statement.
"The bombardment of this hospital is a deplorable act that has cost civilian lives, including medical staff who are dedicated to helping sick and injured people under some of the most challenging conditions," Mughrabi said. "Deliberately targeting medical facilities is a serious violation of international humanitarian law which would amount to a war crime. The circumstances of this attack must be thoroughly and independently investigated."
ABOUT THE YEMEN CONFLICT
1 On one side is Yemen's President Abed Rabbo Mansour Hadi, who is backed by Saudi Arabia, the United States and their allies
2 On the other side is an alliance between Shia Houthi rebels and loyalists of former President Ali Abdullah Saleh. They seized the capital, Sana'a, and drove Hadi southwards to the port city of Aden.
3 Sunni-led Saudi Arabia, concerned about the Houthis and their links to its main regional rival, Iran's Shia theocracy, entered the war to restore Hadi to power.
4 More than 6500 people have died in the war, around half of them civilians.
