At least one teenager was killed and 11 others injured in a blast in Russia’s Republic of Dagestan, where an explosion at a local school was reportedly caused by a grenade brought into the building by one of the students.
At least three of the injured teenagers are in a critical condition, RIA Novosti reported, citing a local hospital.
Investigators are now working at the scene, the official said, adding that anti-terrorist committee is not involved in the case. According to preliminary data, the incident happened due to “careless handling of a weapon,” stated Dagestan’s Interior Ministry spokesman.
The incident happened in the village of Agvali, Dagestan, in Russia’s North Caucasus region.
A grenade exploded in a computer classroom, RIA Novosti cited the school principal, Shamil Abakarov, as saying.
The weapon was allegedly brought into the building by an eighth-grade student, he said.
The ministry confirmed that the student who brought the grenade had been detained. Police are now working with the teenager, Interfax reported, citing the local police press service.
