Russian Ambassador: America did not share any information with us before the Moscow attack. At least 143 people were killed in the attack on the Crocus concert hall in the suburb of Krasnogorsk, northwest of the Russian capital, Moscow.
The Islamic State claimed responsibility for the attack, according to accounts on social media sites that the organization usually uses. The US Embassy in Russia warned its citizens two weeks ago that “extremists have imminent plans to target large gatherings in Moscow, including concerts,” and the White House said the United States shared this information with Russian authorities.
