Russia is experiencing a day of mourning today for the victims of Friday’s attack on the popular Crocus City Hall concert hall, on the outskirts of Moscow.

According to the latest data provided by the authorities this morning, the terrorist attack has caused at least 133 deaths, including three children, and 152 injured, most of whom remain hospitalized, almost fifty in serious condition.

From the early hours of the morning, Muscovites bring flowers to the site of the attack in the city of Krasnogorsk, about 20 kilometers from the center of Moscow.

Already the day before, as EFE was able to verify, a spontaneous memorial appeared next to the concert hall building in which Russians placed bouquets of red flowers and carnations in memory of the victims of the attack.

This Sunday the flags in official Russian institutions and their embassies abroad will remain at half-mast as a sign of mourning. Cultural events and leisure activities throughout the country were also cancelled.

The attack on Crocus City Hall, claimed by the Islamic State, is the largest terrorist attack suffered by this country in two decades after the massacre in Beslan (2004).

Russian President Vladimir Putin stated this Saturday that “all the authors, organizers and those who commissioned this crime will receive a well-deserved and irremediable punishment, whoever they are and regardless of whether they were sent.”

Security forces have so far arrested 11 people linked to the attack, four of whom personally participated in the massacre, according to authorities.

Meanwhile, stories of the victims of the attack, told by their friends and family, are spreading today in Russian media and social networks. Some survivors also share first-hand images from the concert hall during the attack that took those attending the Piknik concert by surprise.

According to official sources, on the day of that group’s performance, more than 6,000 tickets for their concert had been sold out.
