In a statement published on Thursday (9 February), the organisation warned locations frequented by tourists in Nairobi and elsewhere in Kenya continue to be attractive targets to terrorists planning to conduct "potentially imminent" attacks.
Groups could attack with little or no warning, targeting hotels, embassies, restaurants, shopping centres, markets, schools, police stations and places of worship.
The government of Kenya has increased counterterrorism patrols and travellers have been advised to exercise vigilance at locations frequented by tourists, review their security plans, remain aware of their surroundings and monitor local media.
