Input: This is the incredible moment a hotel worker chased the Tunisian gunman moments after he slaughtered 38 innocent tourists including 18 Britons. The unnamed man, who filmed the end of the massacre on his phone, can be seen running after Seifeddine Rezgui as the ISIS militant selects his targets. At one point he even picks up what appears to be a bottle of olive oil as he attempts to sneak up behind the 23-year-old assassin to disarm him. The 11-minute video was released as it emerged the number of Britons killed in Sousse on Friday could reach 30. It also came as Tunisia made its first arrests in connection with the terror attack.Unnamed worker filmed the end of the gunman's rampage on his phoneFollows Seifeddine Rezgui through the hotel grounds and up the beachVideo released as it was revealed British death toll could reach up to 30Group of suspects arrested on Monday, the country's interior minister said
