Kampala, Uganda (CNN) — The U.S. Embassy in Uganda said that it had been warned of a “specific threat” Thursday evening against Entebbe International Airport near the Ugandan capital, Kampala.
An embassy statement, which said the warning came from Ugandan police, based on intelligence sources, said the threat involved an unknown terrorist group.
“Individuals planning travel through the airport this evening may want to review their plans in light of this information,” it said.
The warning comes a day after the Obama administration said it was stepping up security for some flights headed to the United States from Europe and the Middle East, reflecting heightened concern that terrorists are developing more sophisticated bombs designed to avoid airport screening.
Specific steps and airports were not disclosed.
A homeland security official said the Transportation Security Administration would work with airlines and security agencies overseas and that the changes would primarily focus on airports in Europe and the Middle East.
The effort does not involve changes to what travelers can take aboard flights. But passengers may see additional inspections of shoes and electronics, additional use of scanners designed to detect trace amounts of explosives, and another stage of screening at boarding gates, in some cases, the official said.
