U.S. Investigates Yemen Packages Shipped Via UPS, FedEx - Bloomberg U.S. officials are investigating packages sent from Yemen to the U.S. after suspicious parcels were found in the U.K. and Dubai, raising concern that the incident was a dry run for a future terrorist attack. United Parcel Service Inc. said the Federal Bureau of Investigation checked packages today on three jets from Europe, while FedEx Corp. said it embargoed shipments from Yemen after a parcel from the country was seized by officials at its Dubai facility. President Barack Obama was notified late yesterday about a “potential terrorist threat,” the White House said. “Authorities were able to identify and examine two suspicious packages, one in East Midlands, United Kingdom, and one in Dubai,” the White House said in a statement. “Both of these packages originated from Yemen.” Investigators are looking at whether the shipments were staged as rehearsals for a future attack, a U.S. official said. Links to al-Qaeda in the Arabian Peninsula, a branch of the group that operates in Yemen, also are being studied, said the official, who requested anonymity.
