The details are eerily familiar: a family outing, a suicide bomber, more than a dozen people — many of them children — killed in an attack later claimed by the Islamic State.

An explosion early Tuesday at an ice cream parlor in Baghdad shared many of the same heart-wrenching characteristics of last week’s attack at an arena in Manchester, England. And that was just the start of the violence on Tuesday in a city where these kinds of terrorist attacks have actually been on the decline this year.

First, the Islamic State targeted the popular Al Faqma shop in the central Karrada neighborhood of Baghdad, where families had gathered to celebrate iftar and break their daylong fast during the holy month of Ramadan.
