WASHINGTON, July 3 Airlines with direct flights to the United States have been told to tighten screening of mobile phones and shoes in response to intelligence reports of increased threats from al Qaeda affiliated militant groups, U.S. officials said.
The officials singled out smartphones including iPhones made by Apple Inc and Galaxy phones made by Samsung Electronics for extra security checks on U.S.-bound direct flights from Europe, the Middle East and Africa.
U.S. security officials said they fear bombmakers from the Yemen-based al Qaeda in the Arabian Peninsula (AQAP) have figured out how to turn the phones into explosive devices that can avoid detection at airport security checkpoints.
They also are concerned that hard-to-detect bombs could be built into shoes, said the officials, who declined to be identified because of the sensitivity of the issue.
Airlines or airport operators that fail to strengthen security could face bans on flights entering the United States, the officials said, adding that the U.S. government has consulted with international airlines, foreign governments and airport operators on the issue.
The U.S. Homeland Security Department announced on Wednesdey plans to step up security checks, but they offered few details on how airlines and airports will implement them.
U.S. security agencies fear bombmakers from AQAP and the Islamist Nusra Front, al Qaeda's affiliate in Syria, are collaborating on plots to attack U.S. or Europe-bound planes with bombs concealed on foreign fighters carrying Western passports, the officials said.
AQAP has a track record of plotting such attacks. Its innovative bombmaker, Ibrahim al-Asiri, built an underwear bomb used in a failed 2009 effort to bring down a Detroit-bound airliner, and his devices were implicated in other plots.
There was no immediate indication U.S. intelligence had detected a specific plot or timeframe for any attack.
U.S. officials say the United States has acquired evidence that Nusra and AQAP operatives have tested new bomb designs in Syria, where Nusra is one of the main Islamist groups fighting to overthrow President Bashar al-Assad. (Editing by Jason Szep and Andrew Hay)
