Yemen warns of 26 more suspicious packages

Some may have already been sent out of the country.

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.

The plot sent tremors throughout the U.S., where after a frenzied day searching planes and parcel trucks for other explosives, officials temporarily banned all new cargo from Yemen.
