At least 37 people, including British tourists, have been shot dead by a gunman who stormed a beach resort in Tunisia, strafing holidaymakers as they lay on sun loungers and sat beside swimming pools.

The attack in Sousse, a popular resort some 80 miles south of the Tunisian capital, was the third in a series of bloody attacks internationally involving Islamist fighters on 26 of June.
