Iraq's anti-regime protesters gathered in the capital and south on Saturday, grieving but defiant after 17 were killed in an attack demonstrators described as "slaughter".
The protest movement faced another worrying turn on Saturday after an armed drone targeted the home of Iraqi cleric Moqtada Sadr, an attack his office said could lead to "civil war."
"They wouldn't let us evacuate the wounded. It was slaughter."
The US on Friday slammed the presence of Tehran's pointman on Iraq, Major General Qasem Soleimani, as "a huge violation of Iraqi sovereignty."
