U.S. airstrike kills senior al Qaeda leader, Pentagon says Strike was conducted in eastern Afghanistan.

WASHINGTON, D.C. -- An American counter-terrorism airstrike conducted last weekend in eastern Afghanistan killed a senior al Qaeda leader named Qari Yasin, the Pentagon announced Saturday.

Yasin is responsible for plotting a number of high-profile al Qaeda terror attacks, including the 2008 bombing of a Marriott Hotel in Islamabad, Pakistan, and a 2009 bombing that targeted a bus carrying the Sri Lankan cricket team in Lahore, Pakistan.

In addition to the dozens of innocent victims killed in these attacks, the 2008 bombing in Islamabad killed two U.S. military personnel: Air Force Maj. Rodolfo I. Rodriguez and Navy Cryptologic Technician Third Class Petty Officer Matthew J. O’Bryan.

"The death of Qari Yasin is evidence that terrorists who defame Islam and deliberately target innocent people will not escape justice," Defense Secretary James Mattis said in a statement.

Yasin, from Balochistan, Pakistan, had ties to the Pakistan-based terror organization Tehrik-e Taliban.
