Two Britons have been arrested by anti-terror police in Kenya, according to reports.
The pair are thought to have been detained in the beach resort of Diani, on the south coast of the country.
Sources suggested to Sky News they were carrying hand grenades at the time of their arrest.
A Foreign Office spokesman, who said he could not give further details of the incident, said: “We are looking into reports of two British nationals detained in Kenya.
"We stand ready to offer consular assistance."
Two months ago 67 people died in a siege at the Westgate shopping mall in Nairobi.
Four men appeared in a Nairobi court earlier this month charged with "supporting a terrorist group" in connection with the attack.
