Iraqi Prime Minister Mustafa al-Kadhemi announced Saturday the arrest of a “terror cell” behind a Baghdad market bombing that killed dozens and was claimed by the Islamic State group. The attack sparked revulsion and renewed fears about the reach of IS, which lost its last territory in Iraq after a gruelling campaign that ended in late 2017, but retains sleeper cells in remote desert and mountain areas. The bombing took place on Monday at Al-Woheilat market in Sadr City, a Shia suburb in the capital, and officially killed 30 people, excluding the direct perpetrator.
