Washington:

The United States warned Russian authorities earlier in March about a terrorist attack possibly targeting “large gatherings” in Moscow, the White House said Friday, hours after a mass shooting killed at least 60 outside the Russian capital.

“Earlier this month, the US government had information about a planned terrorist attack in Moscow –- potentially targeting large gatherings, to include concerts” and Washington “shared this information with Russian authorities,” National Security Council spokeswoman Adrienne Watson said.
