Water cannons used on protesters in Baghdad

STORY: Iraq’s longest post-election deadlock, at nearly 10 months with no government after an October vote, has led to unrest including protests by supporters of the powerful cleric Moqtada al-Sadr, who are occupying parliament in an open-ended sit-in.

Sadr's opponents include a grouping of parties and militias mostly aligned with Iran.

That grouping, known as the Shi'ite Coordination Framework, called for counter protests on Monday evening near the parliament, saying that was aimed at protecting state institutions against the civil unrest of the Sadrists.
