Moscow, 26 March

Russian President Vladimir Putin said Monday that the gunmen who carried out the concert hall attack that killed over 130 people in a Moscow suburb last week were “radical Islamists.”

Speaking in a meeting with government officials, Putin said the killings were carried out by extremists "whose ideology the Islamic world has been fighting for centuries.”

Putin, who said over the weekend the four attackers were arrested while trying to escape to Ukraine, didn't mention the affiliate of the Islamic State group that claimed responsibility for the attack. He again refrained from mentioning IS in his remarks Monday. He also stopped short of saying who ordered the attack but said it was necessary to find out “why the terrorists after committing their crime tried to flee to Ukraine and who was waiting for them there.”

After the IS affiliate claimed responsibility, US intelligence backed up their claims. French President Emmanuel Macron said France has intelligence pointing to “an IS entity” as responsible for the Moscow attack.

Earlier Monday, Kremlin spokesman Dmitry Peskov refused to assign blame, urging reporters to wait for the results of the investigation in Russia. He also refused to comment on reports that the U.S. warned authorities in Moscow on 7 March about a possible terrorist attack, saying any such intelligence is confidential. As Putin spoke, calls mounted in Russia to harshly punish those behind the attack.

Four men were charged by a Moscow court Sunday night with carrying out a terrorist attack. At their court appearance, they showed signs of being severely beaten. Civil liberties groups cited this as sign that Russia's poor record on human rights under Putin was bound to worsen. Russia's Prime Minister Mikhail Mishustin said the investigation is still ongoing but vowed that “the perpetrators will be punished, they do not deserve mercy.”

Former President Dmitry Medvedev, now deputy head of Russia's Security Council, urged authorities to “kill them all.” The attack Friday night on Crocus City Hall on the western outskirts of Moscow left 137 people dead and over 180 injured, proving to be the deadliest in Russia in years. A total of 97 people remained hospitalized, officials said.

As they mowed down concertgoers with gunfire, the attackers set fire to the vast concert hall, and the resulting blaze caused the roof to collapse. The search operation will continue until at least Tuesday afternoon, officials said. A Russian Orthodox priest conducted a service at the site Monday, blessing a makeshift memorial with incense.
