The U.S. Embassy in Uganda warned on Thursday of a specific threat by an unknown terrorist group to attack the country's only international airport.
The Entebbe International Airport could be attacked on Thursday between 9 p.m. and 11 p.m. local time, the embassy said on its website, citing information obtained from Ugandan police. The statement urged U.S. citizens traveling through Entebbe around that time to "review their plans in light of this information."
There is a "continued threat of potential terrorist attacks in the country," with targets ranging from nightclubs to government offices, the statement said.
The airport, which is about 36 kilometers south of Kampala, the Ugandan capital, was the scene in 1976 of a successful Israeli military operation to rescue dozens of hostages held by pro-Palestinian hijackers.
The warning from the embassy came the day after the U.S. government called for tighter security measures at foreign airportsthat have direct flights to the U.S. There are no direct flights from Uganda to the U.S. Most flights connect through Europe.
Ignie Igundura, the spokesman for Uganda's Civil Aviation Authority, said there were no plans to temporarily close the airport over a terror threat. He said the airport had since taken some security measures that he declined to talk about.
Al-Shabab claimed responsibility for deadly attacks in July 2010 that targeted restaurants and bars showing World Cup games on giant screens in Kampala. The group was also behind an attack on an upscale mall in the Kenyan capital, Nairobi, in which scores were killed.
Both Uganda and Kenya have sent troops into Somalia to battle the militants under the banner of the African Union.
