There are new developments this morning in the war on terror as three suspected U.S. drone strikes have targeted militants in southern Yemen over the last two days. The strikes may have killed as many as 40 militants, including foreigners and Al Qaeda leaders.

Here's more details from FoxNews.com:

A suspected U.S. drone strike in southern Yemen Monday was the third deadly attack on Al Qaeda militants in the area in two days.

Yemeni security officials and tribal chiefs say several Al Qaeda militants were killed Monday -- including a local militant commander-- when a suspected U.S. drone attacked the rugged mountainous area of Mahfad between the provinces of Abyan and Shabwa.

The officials and the elders spoke on condition of anonymity because they were not authorized to talk to media.

Tribal leaders identified the killed commander as Munnaser al-Anbouri. It was unclear how many militants died in Sunday or Monday’s strikes.

The BBC reported three suspected Al Qaeda militants were traveling in a car in Shabwa province early Monday when a missile struck, destroying the vehicle. 

More than 40 fighters may have been killed in drone strikes in the last three days.

An airstrike Sunday targeted suspected Al Qaeda training camps in the same mountain region in southern Yemen, killing a number of fighters, but a high-level government security committee could not provide a specific casualty figure.

The official Yemen news agency SABA quoted an unnamed official from the security committee who said those killed in Sunday’s strike included foreigners and suspected leading figures in Al Qaeda.

Also Sunday, A Yemeni security official says 10 suspected Al Qaeda militants were arrested in Shabwa province.

Martha MacCallum discussed the drone strikes this morning with Rep. Michael McCaul (R-TX), chairman of the House Homeland Security Committee. The strikes come on the heels of the release of a brazen Al Qaeda video, which included Nasir al-Wuhayshi - the suspected leader of Al Qaeda in Yemen - appearing with no mask.

McCaul believes Al Qaeda and militants in Yemen are "perhaps the largest threat" to the U.S. and Europe. He said it's still unclear whether al-Wuhayshi was targeted in the new strikes.

McCaul pointed out that notorious bomb maker Ibrahim Hassan al-Asiri is also active with al Qaeda in Yemen.
