Moscow attack: Putin still absent from tributes, but the Kremlin assures that he is sad. On March 22, gunmen entered Crocus City Hall, a large concert hall near Moscow, before shooting into the crowd and setting the building on fire.
At least 144 people were killed and 695 injured during this attack claimed by the jihadist group Islamic State. Western diplomats, notably American and European, as well as from African and South American countries, went to the site to lay flowers and observe a minute of silence.
