The United Nations has warned that Iraq is at a "crossroads" as a wave of violence killed more than 190 people in four days.
On April 26, UN envoy Martin Kobler, who is in Baghdad, urged all sides to show restraint and avoid the danger of a return to "sectarian civil war."
"I call on the conscience of all religious and political leaders not to let anger win over peace, and to use their wisdom,” he said.
"The latest trouble began on April 23 when security forces moved in against antigovernment protesters near the northern Sunni Arab town of Hawijah, sparking clashes that left 53 people dead.
Dozens more were killed in subsequent unrest, much of it linked to the clashes, and the death toll had reached 195 by April 26.
