Al Qaeda plotted bomb smuggling on board airplanes to USA

And the scary part is that there may be more that haven't yet been intercepted, and could still be somewhere in luggage storages. MSNBC reports (via Hot Air):

After intercepting two mail bombs addressed to Chicago-area synagogues, investigators are searching for two dozen more suspect packages that terrorists in Yemen attempted to smuggle onto aircraft in a brazen al-Qaida terror plot.

Authorities on three continents thwarted the attacks when they seized explosives on cargo planes in the United Arab Emirates and England on Friday. [...]

Several U.S. officials said they were increasingly confident that al-Qaida’s Yemen branch, the group behind the failed Detroit airliner bombing last Christmas, was responsible.

A Yemeni security official said the new investigation involved about 26 suspected packages.

And some of them may still be at large. This is a very chilling case indeed.
