The gates of the Green Zone in Baghdad are made of five-metre-high armoured steel, reinforced with horizontal girders, and strung between concrete pillars and anti-blast walls. Police water cannon trucks are stationed nearby, along with armoured personnel carriers and squads of heavily armed soldiers.
At the first sign of street protests – over failing electricity, unemployment or, more recently, the US-Israeli attacks on Iran – the gates are shut. X-shaped vehicle barriers, made from welded iron beams and mounted on wheels, sit ready at the roadside alongside coils of razor wire; both are slid across the street, sealing off the sprawling neighbourhood, home to the presidential palace, parliament, the prime minister’s office, the massive fortress-like US embassy, and other institutions, including the homes of scores of politicians and members of parliament.
