Daesh group on Saturday claimed responsibility for a massacre in a Tunisian seaside resort that left 39 dead in the worst attack in the country's recent history.

In a statement released on Twitter, the jihadists said the gunman, who they identified as Abu Yahya al-Qayrawani, was a "solider of the caliphate" and most of those killed were "subjects of states that make up the crusader alliance fighting the state of the caliphate".
