The UK is advising against all but essential travel to Sri Lanka after the Easter Sunday bombings in which more than 350 people died.
The Foreign Office says terrorists are very likely to try to carry out indiscriminate attacks there, including in places visited by foreigners.
Eight Britons are known to be among those killed in the attacks on churches and hotels in the Sri Lankan capital Colombo, Negombo and Batticaloa.
More than 500 people were injured.
The Foreign Office has issued advice to any Britons in Sri Lanka:
- Remain vigilant, keep up to date with developments and follow the advice of local security authorities and hotel security staff
- Keep a low profile, avoid crowded public places, large gatherings (including religious gatherings and places of worship) and any demonstrations.
- Avoid travelling during periods of curfew (other than to or from the airport)
- Keep in touch with family and friends and make them aware of any plans you may have
