The Metropolitan police say that they have found “strong” links between the recent beach massacre in Tunisia and an earlier attack in the country.
Metropolitan Police Commander Richard Walton said the beach attack in Sousse which killed 38 tourists, including 30 British nationals, is connected to the killings at the Bardo Museum in the country's capital in March.
"We are now linking evidentially the Bardo Museum investigation with the Sousse investigation," he said.
22 people, most of them foreign tourists, were killed in the terrorist attack which took place at the Bardo Museum in Tunis.
The ISIL terrorist group claimed responsibility for the attack.
The deadly incident gave rise to a diplomatic row between the UK and Tunisia.
London issued a travel advice to British tourists to leave the North African country two weeks after the attack.
The British authorities said Tunisian government failed to do enough not to protect British tourists.
Tunisia introduced several security measures, including arming tourist police, in the wake of the terrorist attack.
