The Foreign and Commonwealth Office (FCO) has changed its travel advice for parts of the Kenyan coast following a spate of attacks that have left at least 87 people dead.
A total of 22 people were killed in raids last Saturday in the village of Hindi in Lamu county, and Gamba in Tana River county, according to the Kenya Red Cross.
In June 65 people were killed when gunmen launched an attack in the coastal town of Mpeketoni.
The Somali militant Islamist group al-Shabab claimed responsibility for the attacks.
In the wake of the killings the FCO is advising against all but essential travel to Lamu county and the areas of Tana River county north of the Tana River itself.
