Iraqi protesters blocked roads in Baghdad on Sunday to raise pressure on the government to resign after more than a week of renewed mass demonstrations. Protesters blocked one road with burning tires and barbed wire, and held up a banner reading “Roads closed by order of the people.” They appeared to be borrowing a tactic from Lebanon, where similar anti-government demonstrations have been underway since Oct. 17, and where protesters have repeatedly blocked major roads. Tens of thousands of protesters have gathered in Baghdad’s central Tahrir Square and across southern Iraq in recent days, calling for the overhaul of the political system established after the 2003 U.S.-led invasion.
