The death toll in a May 26 terrorist blast in south Russia's Stavropol has risen to 8, an emergencies official told RIA Novosti on Tuesday.
More than 40 people were also injured when a bomb went off outside a concert hall in the city.
The latest victim, a 17-year-old boy, suffered massive injuries in the blast.
Security services have arrested six people suspected of organizing and carrying out the attack.
The Stavropol Territory is the largest region in the North Caucasus Federal District, but has remained largely free of the violence that plagues the mostly Muslim neighboring republics, including Ingushetia.
