Yemen-based al-Qaeda responsible for plot

WASHINGTON Officials last Friday intercepted two bombs hidden in packages mailed from Yemen and addressed to synagogues in the Chicago area. Both mail bombs were wired to detonators that used cell phone technology.

U.S. officials have said they believe it was the Yemen group.

The claim was reported by the private SITE Intelligence Group.

The two packages were found on planes traveling through Dubai and Britain, setting off a major security alert in several major cities around the world and in the U.S. Suspicious packages were investigated in Philadelphia, New Jersey and Queens.
