The 2003 U.S.-led invasion of Iraq was meant to topple a dictator who had inflicted reckless wars and economic misery on his fellow Iraqis, and then to usher in a thriving democracy. Instead, Iraqis faced years of upheaval and chaos.
A devastating insurgency, first by Saddam Hussein loyalists and then by al Qaeda, was followed by a sectarian civil war and later the rise of Islamic State, which occupied a third of the country and slaughtered thousands. Here is a look at some of the violence, including suicide bombings and beheadings, that has plagued Iraq, a major OPEC oil producer and key U.S. ally, since the 2003 war.
