The Foreign Office is urging Britons in Kenya to be extra vigilant, warning that terrorists there may be "in the final stages of planning attacks."

The ministry said in travel advice issued today that attacks could be indiscriminate and could target places where expatriates and foreign travelers gather, including hotels, shopping centers and beaches. 

Kenya's military has been fighting militant fighters from the al-Shabab group in neighboring Somalia. Kenyan troops entered Somalia in mid-October to attack the militants, and have been supported by the country's weak army. 

Since then, Ethiopian troops have entered Somalia on the country's west, and they along with African Union troops in Mogadishu are squeezing al-Shabab fighters on three sides.
