An unspecified number of individuals suspected of having links to last Friday’s Tunisian beach massacre have been arrested by Tunisian authorities, Reuters reports. “We will find all those involved, whether it was just logistical support or not,” Najem Gharsalli, the Interior Minister, told reporters. Thirty-nine holidaymakers—mostly Britons—were killed when Tunisian gunman, Saif Rezgui, started firing on the beach by the Imperial Marhaba hotel in Sousse on June 26.
