BELGRADE, Serbia—The gunman suspected in the mosque shootings that left at least 49 people dead in New Zealand had traveled to the Balkans in the past three years, where he toured historic sites and apparently studied battles between Christians and the Ottoman empire.
Authorities in Bulgaria, Turkey, and Croatia have confirmed that Brenton Tarrant, 28, had been to their countries in 2016-2018. Hungarian counterterrorism authorities also suggested that Tarrant had visited but revealed no other information, and local media in Bosnia reported a 2017 trip there.
