At least 11 people have been killed and dozens injured after a "terrorist" went on a rampage at a Russian school - shooting a number of students
Two students were said to have died of injuries they suffered when they jumped out of a third-floor window at school No175 in the city of Kazan.
Videos from Russian news show terrified children jumping out of upper-floor windows to escape the massacre, while others climbed down ladders set up under windows.
The suspect, a 19-year-old man, had reportedly warned on his Telegram social media account that he was planning AN attack, writing in a chilling post:
"You will all be done."
Pupils described scenes of chaos and confusion as the sound of an explosion "thundered" through corridors, followed by gunshots as the killer or killers went from room to room during the attack.
A male was seen in handcuffs as he was led away from the school by armed police.
The suspect was reported to be a former student who graduated four years ago and was currently enrolled at a local university.
Rustam Minnikhanov, president of the oil-rich Tatarstan region, called the suspect a "terrorist" as he confirmed four boys and three girls in the eighth grade were among the dead.
The rampage began when a shooter armed with an automatic firearm walked through the main entrance and immediately opened fire, a source told Russia's Tass news agency.
Pupils and staff ran out of the school in terror as gunfire erupted and police and paramedics raced to the scene, and distraught parents soon began gathering across the road to find out if their children were okay.
It is said that doctors were able to save a ten-year-old boy whose heart stopped beating after he was shot in the head, chest and limbs.
Police reportedly found at least two unexploded bombs in the school, which has more than 1,000 students.
The suspect who was arrested by police told officers he had a bomb inside his home, which was evacuated a short time later, according to reports.
One pupil told local media: “We were sitting on the third floor, we had a history lesson.
“Suddenly, in the middle of the lesson, the headmistress starts shouting into the loud speaker so that no one would open their doors.
“The class teacher quickly closed the door and literally five seconds later a big explosion thundered either on the first or on the second floor.
“We stayed together and did not open the door to anyone, but they burst into it - shots were heard, banging on the door, as if someone was trying to knock it out."
