A medical liaison team has been dispatched to Tunisia to help those affected by the beach massacre, which has left at least 15 Britons dead.
Home Secretary Theresa May said the British death toll remains at 15, but the number is expected to rise as more information comes out.
Speaking after chairing a meeting of the Government's emergency cobra committee this morning, Mrs May said the Government was also sending a team to look at security arrangements in the area, which attracts thousands of western tourists every year.
A total of 38 people were killed in the attack at a beach resort in Sousse on Friday, while 39 others were wounded.
The Foreign Office has updated its travel advice to warn that further terrorist attacks in Tunisia are possible and urged people to be vigilant.
