The death toll in Friday's Moscow concert hall attack has gone up to 93. Meanwhile, eleven people were arrested on Saturday for their involvement in the attack, the Kremlin said.

Among those arrested were four 'terrorists', according to the reports.

Russian lawmaker Alexander Khinshtein said the attackers had fled in a Renault vehicle that was spotted by police in Bryansk region, about 340 km (210 miles) southwest of Moscow on Friday night and disobeyed instructions to stop, news agency Reuters reported.

He said two were arrested after a car chase, while the other two fled into a forest. From the Kremlin account, it appeared they too were later detained.

Khinshtein said a pistol, a magazine for an assault rifle, and passports from Tajikistan were found in the car.

Multiple fatalities were reported after assailants burst into the concert hall in western Moscow and sprayed the crowd with gunfire.

The Islamic State group claimed responsibility for the attack in a statement posted on affiliated channels on social media.

The attack was the deadliest in Russia in years and left the concert hall in flames.

Soon after the incident, a fleet of emergency vehicles were seen gathering outside the ruins of Crocus City Hall, a shopping mall and music venue with a capacity of more than 6,000 people in Krasnogorsk, on Moscow’s western edge.

Friday’s attack came just days after Putin cemented his grip on power in a highly orchestrated electoral landslide.

Videos widely shared on social media showed gunmen at the venue shooting civilians at point-blank range.

The roof of the theatre, where crowds had gathered for a performance by the Russian rock band Picnic, collapsed in the early hours of Saturday morning as firefighters spent hours fighting a fire which erupted during the attack.
