U.S. calls for more transparency in Saudi strike on Yemeni school bus

The top U.S. air commander in the Middle East is urging the Saudi-led coalition of Arab nations to be more forthcoming about an investigation into an airstrike in northern Yemen earlier this month that struck a school bus, killing more than 40 children.

The comments by Lt. Gen. Jeffrey L. Harrigian reflected increasing exasperation by U.S. officials over the conflict that has spiraled into a humanitarian disaster.

“There’s a level of frustration we need to acknowledge,” Harrigian said last week. “They need to come out and say what occurred there.”

His comments were the latest, and bluntest, public critique of the Saudi-led air campaign against Houthi rebels that have been voiced by a growing number of senior U.S. military, Pentagon and diplomatic officials seeking to distance the United States from the conflict — but who are facing increasing questions about U.S. support for the air war with every strike.

The United Nations condemned a separate airstrike south of the contested port city of Hodeida on Thursday that relief officials said killed 27 civilians, including 22 children. “What is happening in Yemen is unthinkable,” said Lise Grande, the United Nations’ humanitarian coordinator in the country.

Harrigian is a former F-22 fighter pilot who is stepping down this week after two years commanding U.S. air operations in the Middle East and Southwest Asia from his headquarters in Qatar. He has played a personal role in trying to persuade — and sometimes cajole — Saudi officials overseeing the air campaign to develop targeting procedures to avoid civilian casualties.

The general would not speculate how or why the school bus was struck, saying that was the focus of the ongoing investigation. “Clearly, we’re concerned about civilian casualties, and they know about our concern,” Harrigian said.

Harrigian’s remarks echoed those of another senior U.S. officer, Lt. Gen. Michael X. Garrett, head of U.S. Army forces in the Middle East. He was directed by Defense Secretary Jim Mattis two weeks ago during a visit to Riyadh, the Saudi capital, to urge officials there to carry out a detailed inquiry into the school-bus bombing.

“He pressed the Saudis to devote the resources and oversight required to do a thorough and complete investigation and release the results to the public,” said Lt. Cmdr. Rebecca Rebarich, a Pentagon spokeswoman.

Yemen’s conflict began in 2014 when Houthi rebels, who are aligned with Iran, seized control of the capital, Sanaa, and sent the government into exile. In March 2015, Saudi Arabia — Iran’s chief rival for power and influence in the Middle East — formed a coalition of Arab nations and launched a military intervention to Yemen’s government. It has so far failed to do so.

U.S. military leaders, frustrated by strikes that have killed civilians at markets, weddings and funerals, have struggled to describe what they say is an arms-length role in the war.

Since 2015, the United States has provided the Saudi-led air campaign in Yemen with midair refueling, intelligence assessments and other military advice. U.S. advisers say they do not give direct or indirect approval on target selection or execution of bombings. Rather, they give advice on targeting procedures and facilitate checks of a list of “no-strike” buildings, like mosques and marketplaces.

Congress has shown increasing concern about the war recently. A defense policy bill that President Donald Trump signed this month included a bipartisan provision that requires Secretary of State Mike Pompeo to certify that Saudi Arabia and its close ally the United Arab Emirates are taking steps to prevent civilian deaths. Without the certification — or unless a national security waiver is invoked — the legislation bars the U.S. refueling of coalition jets.
