- At least seven students, one teacher and another worker were fatally shot when a gunman opened fire at an elementary school Tuesday in the Russian city of Kazan, according to the mayor's office and other Russian officials.
"The terrorist has been arrested". Minnikhanov said it wasn't clear yet whether the gunman had accomplices or acted alone.
Minnikhanov added that 18 students and three adults have been hospitalized with injuries of varying severity.
Police said they had opened an investigation into the attack.
Authorities said additional security measures have been put into place in all schools in Kazan, the capital of Russia's Tatarstan region, which is roughly 700 kilometres (430 miles) east of Moscow.
School shootings are relatively rare in Russian Federation, but authorities have been on guard since a 2018 incident at a polytechnic college in Kerch, Crimea. The siege ended in gunfire and explosions, leaving 334 dead, more than half of them children.
Local media initially reported that there were two suspects but authorities later said the incident was carried out by a lone attacker.
In 2018, a teenager killed 20 people at his vocational school before killing himself in Kerch, a city in the Russian-annexed peninsula of Crimea.
The Kremlin sent a plane with doctors and medical equipment to Kazan, and the country's health and education ministers headed to the region.
