There May Be More Mail Bombs, Feds Warn

US counterterrorism officials have warned local law enforcement and emergency personnel to be on the watch for suspicious mail, in the wake of last week’s foiled mail bomb plot. The FBI and Homeland security have warned post offices to flag packages of foreign origin without return addresses, or with excessive postage, according to a memo obtained by the AP.

Many major cargo firms suspended shipments from Yemen today, and Germany refused to accept even passenger flights; one of the bombs was routed through Cologne en route to London. Officials in the United Arab Emirates meanwhile are tracing the serial numbers on the mobile phone and printer that were turned into a bomb and sent aboard a passenger flight in Dubai.
