The attack on a Moscow concert hall in which armed men opened fire and set the building ablaze, killing at least 133 people, was the latest in a series of bombings and sieges that have unsettled and outraged Russians during Vladimir Putin’s nearly quarter-century as either prime minister or president.

Friday’s attack on the Crocus City Hall, for which a faction of so-called Islamic State in Afghanistan claimed responsibility, followed several years of quiet.
