Authorities in the U.S. Britain and the Middle East have increased security measures at airports and air-cargo facilities after suspicious packages were found on cargo planes bound for the U.S. The White House says President Barack Obama was informed of a potential terrorist threat Thursday. A White House statement says U.S. authorities have been directed to take steps to ensure the safety of the American people and determine whether the threats are part of "any additional terrorist plotting." Authorities say passengers will face enhanced security at the nation's airports. Spokesman Robert Gibbs says intelligence and law enforcement officials on Thursday discovered potential suspicious packages on two UPS cargo planes that were on their way to the United States. He said two suspicious packages that originated from Yemen were found in Britain and Dubai. Shipping giant FEDEX on Friday suspended all deliveries from Yemen after a suspicious package from Yemen was confiscated in Dubai.  At least one of the packages found in Britain contained a toner cartridge with white powder and wires.
