The United States warned its citizens in Uganda on Thursday about a "specific threat" of an attack within hours on Entebbe International Airport, which is near the capital Kampala, according to a message on the US Embassy website.
It said information from Uganda's police indicated that the attack could take place between 9 p.m and 11 p.m. local time (1800 GMT and 2000 GMT) on Thursday, adding that citizens planning to travel at that time might consider reviewing their arrangements.
