The video document released by the jihadist group Islamic State through the Telegram platform from the terrorist attack on the Crocus City Hall concert hall in Krasnogorsk near Moscow is considered authentic and shows the horror experienced by hundreds of people who managed to escape the rampage of armed men to kill.

The 1 minute 31 second video captures shocking images of the moment gunmen opened fire indiscriminately inside Krasnogorsk’s Crocus City Hall, spreading death.

The video shows one of the Kalashnikov brand assault rifles, with a handle on its upper part, which has a characteristic fluorescent color and is present in the documents.

It is recalled that ISIS took responsibility for the attack, while it also posted a photo of the perpetrators of the massacre, however, the Russian president, Vladimir Putin, in his speech yesterday, Saturday, insists on talking about the connection of the armed with the Ukrainian side.

At least 135 people were killed and dozens injured in one of the deadliest terrorist attacks in recent years in Russia.

What we know so far about the attack

Four men, armed with Kalashnikov assault rifles, arrived at Crocus City Hall at around 19:40 local and Greek time in a minivan. Moscow: The four arrested are not Russian citizens

The men calmly walked towards the metal detectors at Crocus City Hall, point-blank shooting the terrified citizens as they fell screaming to the ground in a hail of bullets. Russia: 29 people have been identified out of the 133 killed in the Moscow attack

Russian media began reporting around 20:15 local time about the attack at the concert hall in Krasnogorsk, on the northwestern outskirts of the Russian capital.

Rescue services, as reported by the Interfax news agency, said the attackers “opened fire on security members at the entrance to the concert hall” before “starting to shoot at the crowd”.

According to a reporter for the state-run Ria Novosti news agency, people in camouflage uniforms stormed the hall before opening fire and throwing “a grenade or an incendiary bomb, which caused a fire.”

“The people in the hall fell to the floor to protect themselves from the fire for about 15-20 minutes, after they started running out in panic,” said the same source.

Russian investigators described how the men set fire to the building. Some eyewitnesses said they poured some kind of flammable liquid on the seats and curtains before setting it on fire.

An AFP journalist who arrived hours after the attack saw black smoke and flames rising above the roof of the concert hall, which can accommodate up to 6,000 people. According to media, a part of the roof collapsed. The fire was then brought under control.

The Account

Russia’s Investigative Committee announced that the death toll was 133, but Margarita Simonyan, a journalist for Russian state television and head of Russia Today, spoke of 143 dead.

According to some sources 145 people have been injured. The Moscow Region announced that 121 people had been injured. Earlier, he had reported that 60 of the injured were in critical condition.

According to the Ministry of Emergency Management, firefighters managed to evacuate around 100 people who are in the basement of the concert hall. Operations carried out by the authorities also allowed to “rescue people who had taken refuge on the roof of the building with the help of lifting equipment”.

Taking Responsibility

The Islamic State jihadist group claimed responsibility for the attack, according to a post by the Amaq propaganda outlet on Telegram, about four hours after the shooting began.

“The attack was carried out in the context of the war raging between the Islamic State and countries fighting Islam,” Amaq added in a statement.

The US has intelligence information that corroborated Islamic State’s claim of responsibility for the deadly attack, two US officials said yesterday.

Officials said the U.S. warned Russia in recent weeks of the possibility of an attack, a move they say prompted the U.S. Embassy in Moscow to issue a warning to Americans.

Two weeks ago the US embassy in Russia warned that “extremists” had imminent plans for an attack on Moscow.

Russian President Vladimir Putin said during a televised address to the Russian people that the four men who carried out the attack near Moscow were heading to Ukraine when they were arrested and hoped to cross the border.

“They tried to hide and moved to Ukraine, where, according to preliminary data, a ‘window’ had been prepared for those from the Ukrainian side to cross the border,” Putin said.

Ukrainian military security spokesman Andriy Yusov told Reuters: “Ukraine is of course not involved in this terrorist attack.”

The perpetrators

Russia’s Federal Security Service (FSB) announced that it had arrested 11 people, including four men who carried out the attack. Russian media reports that the men fled the scene of the attack in a white vehicle and that they were arrested in the Bryansk region, 340 kilometers from Moscow.

Some of those arrested are seen being interrogated on the side of the road in videos released by Russian media and Telegram networks with close ties to the Kremlin.

“I shot people,” one of the suspects says in heavily accented Russian, his hands tied and his hair pulled by an interrogator, a black boot under his chin. He said that he was born on September 17, 1998 and that his name is Samsudin Faridun.

When asked why, he replies: “For the money.” He claims he was promised half a million rubles (just over $5000) on Telegram, where he was listening to a preacher.

The man is asked if he was in Turkey on March 4 and he says yes. They told them where gun stores were located and he bought guns there, he claimed.

One of the suspects is seen speaking with the help of an interpreter from Tajikistan. Another is seen being carried out of a forest, his face covered in blood, evident from a wound to the ear.

During interrogation, he answered that his name was Rajab Alizadeh. He had difficulty giving his date of birth in Russian.
