The Kenyan government has warned its citizens not to travel through London Heathrow because of a "substantial threat of possible attack" by Al Qaeda.
The move appears to be a direct response to travel advice issued just hours earlier by the British Foreign and Commonwealth Office, recommending against "all but essential travel" to parts of Kenya following attacks that have left dozens dead.
Karanja Kibicho, the principal secretary of Kenya's ministry of foreign affairs, then announced that the UK is the most likely location for Al Qaeda to bring down a plane.
He told the Daily Nation newspaper: "According to information provided by US officials, Al Qaeda operatives in Yemen and Syria were developing sophisticated bombs that could bring down a plane...
"The information states that Britain would be the most likely country to be affected. Based on this information, Kenyans are advised not to travel through London Heathrow where there is substantial threat of a possible attack."
A spokesman for Heathrow Airport declined Business Traveller's request for a comment.
