London, June 27
 At least five Britons were killed in an attack in Tunisia on Friday, British Foreign Secretary Philip Hammond said on Saturday.

Dozens of people, including foreign tourists, were killed after gunmen opened fire in the Tunisian resort town of Sousse, according to Tunisia's interior ministry.

While 37 people have been confirmed dead in the attack, the number of injured has risen to 36, Xinhua news agency reported.

After chairing an emergency meeting in London, Hammond said on national TV: "The situation on the ground is still somewhat confused and we can't be sure exactly how many, but because of the nature of the composition of the tourist population in this part of Tunisia we have to assume that a high proportion of those killed and injured are British."

He also warned that the toll of British nationals in the attack could rise.
