Iraqi counter-terrorism forces may be forced to intervene after protestors storm parliament

Hundreds of anti-government protesters have climbed over the blast walls surrounding Baghdad's highly-fortified Green Zone for the first time and stormed into the Iraqi parliament.

The breach marks a major escalation in the country's political crisis following months of anti-government protests, sit-ins and demonstrations by supporters of influential Shia cleric Muqtada al-Sadr.
