Five days after the attack on Friday, which was the deadliest claimed by Daesh on European soil and the worst in Russia in two decades, the Russian ministry for civil defense and emergency situations released the names of the deceased.

Approximately 80 people who were injured in the attack, including six children, were still in the hospital, and an additional 205 people had received outpatient care.

Russian Deputy Prime Minister Tatiana Golikova mentioned that many people in shock had initially not returned to the hospital for treatment.

On Friday, gunmen attacked and set fire to the Crocus City concert hall near Moscow, resulting in several arrests.

Four suspects, all from Tajikistan, are in pre-tal detention until May 22.

Russia has arrested 11 people in connection to the attack, but the identities and whereabouts of the other seven are unknown.

Daesh claimed responsibility for the attack, but Moscow has linked it to Ukraine, which Kyiv denies.

Russia has been a target of Daesh due to its involvement in suppressing unrest in Muslim-majority regions and supporting Syria's regime.

On Monday, three days after the attack, President Vladimir Putin acknowledged that the suspected gunmen were radical Islamists.

However, Putin still maintained a connection to Ukraine, claiming the perpetrators were en route there when they were apprehended about 150 kilometers (93 miles) from the border.
