A third gunman in the massacre of tourists in Tunisia's Bardo Museum is still at large after two others were killed, Tunisian President Beji Caid Essebsi said Sunday.
"Definitely there were three," Essebsi told Itele television and Europe 1 radio, adding that the third attacker was "still" at large. The gunmen killed 21 people Wednesday at the National Bardo Museum in Tunis, all but one of them foreign tourists.
