BAGHDAD: Iraqi security forces Friday opened fire on dozens of protesters gathering in Baghdad for a fourth day of demonstrations against corruption, unemployment and poor public services, an AFP correspondent reported. The security forces fired directly at the protesters, not in the air, the correspondent said. There was no immediate word on any casualties. Earlier Friday, Iraq’s prime minister has addressed the nation over the turmoil gripping the country, calling on protesters to go home and saying their demands have been heard. Prime Minister Adel Abdul-Mahdi says that the security measures imposed in the wake of this week’s violence, including the temporary curfew, are “difficult choices” but are needed like “bitter medicine” that has to be swallowed. Iraqi security forces have imposed a round-the-clock curfew in Baghdad. Since Tuesday, they fired live rounds and tear gas every day to disperse anti-government protests, leaving 33 people dead and wounding hundreds. The prime minister’s speech was televised. He told protesters their “legitimate” demands in countering corruption and providing jobs have been heard and that it’s “important to help the government perform its duty toward you.”
