Buses loaded with tourists began leaving the Tunisian resort of Sousse on Friday after a gunman opened fire on European sunbathers, killing at least 37.
Several buses left a hotel in the Port El-Kantaoui neighbourhood of Sousse, near the beach where the attack happened only a few hours earlier.
The Deputy British Ambassador in Tunisia, Rufus Drabble, set up an emergency response team to provide assistance to British and Irish tourists still at the hotel.
The Health Ministry said the 37 dead included Tunisians, British, Germans and Belgians, without giving a breakdown.
