WASHINGTON—U.S. officials said Monday they are looking into reports that the leader of al Qaeda's affiliate in Yemen, considered one of the group's most dangerous spinoffs, was killed in an airstrike there.

Twitter accounts used by militants have circulated claims that Nasser al-Wuhayshi, leader of al Qaeda in the Arabian Peninsula, or AQAP, was killed in a U.S. airstrike, the SITE monitoring group reported Monday.

"If confirmed, the death of AQAP's leader is a major blow to Islamist terrorists who are plotting daily to attack America," said Rep. Michael McCaul (R., Texas), chairman of the House Committee on Homeland Security.

AQAP has been linked to numerous terrorist attacks, including the killings earlier this year at a French satirical magazine in Paris.

The U.S. government had offered a $10 million reward for information leading to the death of Mr. Wuhayshi, making him one of the U.S. government's most-wanted terrorists.

In 2013, al Qaeda leader Ayman al Zawahiri is believed to have elevated Mr. Wuhayshi to the position of a "general manager," which some U.S. officials believe makes him second in command of the whole al Qaeda organization.

Mr. Wuhayshi was Osama bin Laden's personal secretary and has long known Mr. Zawahiri. He escaped from a Yemeni prison in 2006 and assumed control of the Yemen group in 2009, drawing on al Qaeda's defunct Saudi branch.

Among his early recruits was a Saudi bomb-maker Ibrahim Hassan Tali al-Asiri, who became one of the terrorists most feared by the U.S. for his creative bomb-making skills.

It couldn't immediately be learned whether a recent U.S.-directed drone attack targeted Mr. Wuhayshi. Both the Central Intelligence Agency and the U.S. military have conducted drone strikes in Yemen in recent years, taking out some of AQAP's top leadership. Yemen's recent political chaos and civil war have disrupted some U.S. efforts, but American officials have said the counterterrorism campaign there hasn't let up.

Max Abrahms, a terrorism expert at Northeastern University, said al Qaeda has tried recently to present itself as a more moderate force in Yemen in a multifaceted conflict involving Houthi rebels. In Syria, the al Qaeda-affiliated Nusra Front has battled against Islamic State militants as well as Syrian President Bashar al-Assad.

Some coalition partners have begun to view the group more favorably, as a counterweight to Islamic State. The U.S. strike, if confirmed, could represent the U.S. commitment to disrupting al Qaeda, Mr. Abrahms said.

"The U.S. is partly trying to show we're anti-al Qaeda," he said. "We're still going after their leaders."
