From St. Petersburg to Crocus City Hall: How U.S. warnings of terrorist attacks in Russia have played out

On October 31, the U.S. Embassy in Moscow issued a warning of a potential terrorist attack at the Tsaritsyno museum and park complex. The Federal Security Service (FSB) confirmed receiving this warning from the United States, leading to the complex's closure for "technical reasons." No attack took place.

Two days later, the FSB announced they had detained a teenager who allegedly provided information about a planned attack. This is not the first instance of the U.S. sharing information with Russian authorities regarding potential terrorist attacks in Russia. Here are three notable cases.

In December 2017, the FSB stated they had detained seven members of the Islamic State group who allegedly planned to bomb Kazan Cathedral in St. Petersburg. Two days after their detention, the Kremlin acknowledged that the CIA had provided critical information that thwarted the attack. Russian President Vladimir Putin expressed gratitude to U.S. President Donald Trump for the timely intelligence.

In December 2019, the Kremlin reported that Putin had also called Trump to thank him for intelligence that helped prevent terrorist attacks in Russia. Subsequently, the FSB announced the detention of two Russian nationals who intended to carry out an attack in St. Petersburg during the New Year holidays, alleging they were members of the Islamic State group. One of the detained individuals received an eight-year sentence, while the other's sentence was not publicly reported.

On March 2024, the U.S. Embassy warned of possible terrorist attacks in Moscow within the next two days. No attack occurred during that time, which President Putin dismissed as "provocative statements." Less than two weeks later, a terrorist attack at Crocus City Hall resulted in 150 deaths. The FSB later acknowledged that U.S. intelligence agencies had warned Moscow about an imminent attack, although they characterized the information as "general nature."

Sources cited by Western media claimed the information was far more specific, including Crocus City Hall as a potential target.
