The U.N. humanitarian chief Mark Lowcock condemned massacre of civilians by Saudi-led coalition on Friday in two major airstrikes in Yemen.

Undersecretary General for Humanitarian Affairs Mark Lowcock said a Saudi-led coalition airstrike on Thursday killed at least 22 children and four women fleeing fighting in Al Durayhimi district in Hodeida governorate of Yemen.

An additional airstrike by Saudi-led coalition in Al Durayhimi on Thursday killed four children, Undersecretary General for Humanitarian Affairs added.

Lowcock said he echoed Secretary-General Antonio Guterres’ call for “an impartial, independent and prompt investigation into these most recent incidents.”

On Aug. 9, coalition airstrikes hit a bus in a busy market in Saada governorate in Yemen’s north, killing at least 51 people including 40 children. The attack drew broad international condemnation and the coalition said it would investigate.

Henrietta Fore, executive director of the U.N. children’s agency, UNICEF, said she hoped the Saada attack “would be a turning point in the conflict,” but Thursday’s attacks “indicate that it was not.”

“I — once again — call for the warring parties, those who have influence over them, the U.N. Security Council and the international community to take action and end this conflict once and for all,” Fore said in a statement. “The lives of thousands of vulnerable children across Yemen must be a priority for all.”

In Aug.10, UN Secretary-General Antonio Guterres calls for an independent and prompt investigation into the deadly Saudi-led coalition airstrike that hit a school bus in Yemen .

The conflict in impoverished Yemen began with the 2014 takeover of the capital of Sanaa by Houthi Shiite rebels, which toppled the internationally recognized government. A Saudi-led coalition allied with the government has been fighting the Iranian-aligned Houthis since 2015.

Civilians have borne the brunt of the conflict which has pushed Yemen to the brink of famine, crippled the country’s health system, and killed over 10,000 people.

The Houthis had blamed Thursday’s attack in Hodeida on the coalition.

Lowcock’s condemnation of the recent coalition airstrikes follows the release earlier Friday of a 90-page report by Human Rights Watch accusing the Saudis and others of failing to conduct credible investigations into war crimes committed in Yemen or redress the toll on civilians.

Undersecretary General for Humanitarian Affairs stressed that the humanitarian operation in Yemen is currently the largest in the world, with three-quarters of the population in need of aid.

In 2018, he said, the U.N. and its partners assisted more than 8 million people.

Lowcock expressed deep concern at the proximity of attacks to humanitarian sites including health facilities and water and sanitation operations.

“The parties to the conflict must respect their obligations under international humanitarian law and those with influence over them must ensure that everything possible is done to protect civilians,” Undersecretary General for Humanitarian Affairs said.

Also, Frank McManus, Yemen country director for the International Rescue Committee urged the United States, United Kingdom and France to use their leverage to alleviate suffering, saying “Yemen, and Yemenis, cannot wait.”
