The Kremlin announced on Monday that it would not take part in talks on reinstating the death penalty, a move that several of President Vladimir Putin’s allies are already saying after Russia’s deadliest attack in two decades.

Four men have been arrested and charged with terrorism following Friday’s attack on a concert hall on the outskirts of Moscow that killed at least 137 people and injured 182 others. And many officials spoke about restoring the death penalty.

“Many people are now asking questions about the death penalty. This topic will certainly be studied in depth, professionally, significantly,” said Volodymyr Vasiliev, the leader of the United Russia faction in the lower house of the parliament, quoted by the state news agency TASS on Saturday.

Dmitry Medvedev, a Putin ally and former one-term president of Russia who has become a radical voice on Ukraine and the West over the past two years, was much more direct.

“Do they have to be killed? So. And they will be,” he said in a Telegram post.

Also on Monday, the Kremlin said it would not take part in the debate on lifting the moratorium on the death penalty.

“We are not taking part in this discussion now,” Kremlin spokesman Dmytro Peskov said at the daily briefing.

The death penalty is legal in Russia, but no executions have taken place since 1996, when President Boris Yeltsin issued a decree establishing a de facto moratorium, which was directly upheld by the Constitutional Court in 1999.

Russia’s criminal code currently provides for the death penalty for five crimes: murder, genocide, and attempted murder committed by a judge, police officer, or public official.

Arrest and torture

The Basmanny District Court of Moscow on Sunday granted the request of the prosecutor’s office for preventive arrest for two months for all four suspects in the case of the attack on Friday.

The FSB reported the arrest of the alleged attackers in the Bryansk region on Saturday, Meduza notes. The men were driving towards the Russian-Ukrainian border, the Russian authorities claim.

Several photos and videos appeared on Russian Telegram channels, showing two of the four men, Shamsidin Faridouni and Saidakrami Rachebalizoda, being tortured by security forces during interrogation.

Saidakrami Raceabalizoda allegedly cut off her ear during the interrogation and then forced her to eat it, reports Meduza.

Russian Telegram channels published an image of Shamsidin Faridouni lying on the ground shirtless and being tortured with an electric current to his genitals.

Muhammadsober Faizov was brought to the courtroom in a wheelchair. After his arrest, he was hospitalized. In court, he did not react in any way to what was happening around him.

Dalerjon Mirzoev appeared in the courtroom with a broken eye and a torn bag around his neck.
