US authorities specifically warned Russia that the Crocus City Hall near Moscow was a possible target for attackers. This is what insiders say to The Washington Post newspaper. Russian authorities have actually stated that American warnings were not detailed enough.
A bloody attack took place at the concert hall last month, resulting in 144 deaths. Russian authorities have acknowledged receiving information from American intelligence services, but it would have been too general to prevent the tragedy.

The US more often warns countries when an attack is imminent. According to the newspaper, it is unusual for this kind of detailed information about the possible target to be shared with a rival power. This could inadvertently reveal how the Americans obtained their intelligence.
The attack was claimed by ISIS-Khorasan, one of the most feared branches of the terrorist organization. Despite the fact that the cell has claimed responsibility, Russian President Vladimir Putin still points to Ukraine as the sponsor of the attack. However, no evidence has been provided for this.
