US Airlines Warned Over Possible Shoe Bombs
Airlines flying to the United States have been warned to be on alert for explosives hidden in shoes.
It is the second time in less than three weeks the US government has raised concerns over possible attempts to smuggle explosives onto commercial jetliners.
The Department of Homeland Security (DHS) declined to discuss specific details about the warning but said it regularly shares relevant information with domestic and international partners.
"Our security apparatus includes a number of measures, both seen and unseen, informed by the latest intelligence and as always DHS continues to adjust security measures to fit an ever evolving threat environment," the department said in a statement.
The latest warning was focused on flights headed to the United States from abroad.
A US intelligence official told the AP news agency that "something caused DHS concern, but it's a very low threshold to trigger a warning like this".
Earlier this month, DHS warned airlines with flights to Russia to be on the lookout for explosive devices possibly hidden inside toothpaste.
The Transportation Security Administration then banned passengers from bringing any liquids in their carry-on luggage on non-stop flights from the US to Russia.
That warning became public just days before the opening ceremonies of the Winter Olympics in Sochi.
In 2001, Richard Reid tried to ignite two bombs packed into his shoes aboard an American Airlines flight from Paris to Miami.
Reid was overpowered by passengers and crew before he could detonate the explosives. He is currently serving a life sentence.
