Iran alerted Russia to security threat before Moscow attack, sources say
Tehran gained information from suspects linked to Kerman bombing in Iran, but material it provided to Russians lacked specific details of ISIS-Khorasan plans
DUBAI, April 1 (Reuters) — Iran tipped off Russia about the possibility of a major “terrorist operation” on its soil ahead of the concert hall massacre near Moscow last month, three sources familiar with the matter said.
In the deadliest attack inside Russia in 20 years, gunmen opened fire with automatic weapons at concertgoers on March 22 at the Crocus City Hall, killing at least 144 people in violence claimed by the Islamic State group.
The United States had also warned Russia in advance of a likely militant Islamist attack but Moscow, deeply distrustful of Washington’s intentions, played down that intelligence.
It is harder, however, for Russia to dismiss intelligence from diplomatic ally Iran on the attack, which has also raised questions over the effectiveness of Russian security services. Moscow and Tehran, both under Western sanctions, have deepened military and other cooperation during the two-year Ukraine war.
“Days before the attack in Russia, Tehran shared information with Moscow about a possible big terrorist attack inside Russia that was acquired during interrogations of those arrested in connection with deadly bombings in Iran,” one of the sources told Reuters.
Iran arrested 35 people in January, including a commander of Islamic State’s Afghanistan-based branch ISIS-Khorasan (ISIS-K), who it said were linked to twin bombings on January 3 in the city of Kerman that killed nearly 100 people.
Islamic State claimed responsibility for the Iran blasts, the bloodiest since the 1979 Islamic Revolution. US intelligence sources said ISIS-K had carried out both the January 3 attacks in Iran and the March 22 shootings in Moscow.
Islamic State once occupied large swaths of Iraq and Syria, imposing a reign of terror and inspiring lone wolf attacks in Western countries, but was declared territorially defeated in 2017.
However, ISIS-K, one of its most fearsome branches, has raised the group’s profile again with large-scale bloodshed.
ISIS-K, named after an old term for a region that encompassed parts of Iran, Turkmenistan, and Afghanistan, emerged in eastern Afghanistan in late 2014 and quickly established a reputation for extreme brutality.
‘Significant operation’
A second source, who also requested anonymity due to the sensitivity of the issue, said the information Tehran provided to Moscow about an impending attack had lacked specific details regarding timing and the exact target.
“They (the members of ISIS-K) were instructed to prepare for a significant operation in Russia… One of the terrorists (arrested in Iran) said some members of the group had already traveled to Russia,” the second source said.
A third source, a senior security official, said: “As Iran has been a victim of terror attacks for years, Iranian authorities fulfilled their obligation to alert Moscow based on information acquired from those arrested terrorists.”
Asked about the Reuters report, Kremlin spokesman Dmitry Peskov said on Monday: “I do not know anything about this.”
Iran’s foreign ministry did not reply to a request for comment on this story. The White House had no comment on the matter.
A source familiar with the US intelligence on an impending attack in Russia said it was based on interceptions of “chatter” among ISIS-K militants.
Challenging the US assertions, Russia has said it believes Ukraine was linked to the attack, without providing evidence. Kyiv has strongly denied the assertion.
Tajik nationals
The attacks in Kerman and near Moscow both involved Tajik nationals. ISIS-K has aggressively recruited from the impoverished former Soviet republic of Tajikistan, security experts say.
Sources said Iran had discussed its security concerns with Tajikistan. A diplomatic source in Tajikistan confirmed that Tehran had recently discussed with Dushanbe the issue of increased involvement of ethnic Tajiks in militant activities.
Islamic State harbors a virulent hatred for Shi’ites — Iran’s dominant sect and also the target of its affiliate’s attacks in Afghanistan. The hardline Sunni Muslim group views Shi’ites as apostates.
In 2022 the Islamic State claimed responsibility for a deadly attack on a Shi’ite shrine in Iran that killed 13 people. Tehran identified the attacker as a Tajik national.
Earlier attacks claimed by Islamic State include twin bombings in 2017 that targeted Iran’s parliament and the tomb of the Islamic Republic’s founder, Ayatollah Ruhollah Khomeini.
