Militants may be on the verge of launching terror attacks in the Kenyan capital Nairobi, the British Foreign Office has warned in an alert to Britons in the African country.
The Kenyan authorities, who are engaged in military action against al-Shabab militants in southern Somalia and reportedly killed 50 in an air strike yesterday, have increased security in the city.
In an update to its travel advice, the Foreign Office said: "The Kenyan authorities have alerted the public to a heightened threat from terrorist attacks in Nairobi.
"We believe that terrorists may be in the final stages of planning attacks. Attacks could be indiscriminate and target Kenyan institutions as well as places where expatriates and foreign travellers gather, such as hotels, shopping centres and beaches.
"We strongly advise British nationals to exercise extra vigilance and caution in public places and at public events."
It already cautioned against all but essential travel to the city's poorest areas, including townships and slums.
