Dozens Killed in Iraq as Protests Escalate VOA News Iraqi security forces used live ammunition against mostly unarmed demonstrators Thursday, killing at least 40 people in one of the bloodiest days since anti-government protests began last month, security and medical officials said. At least 25 people were killed and more than 200 wounded when security forces opened fire on protesters who had blocked key roads and bridges in the southern city ofNasiriyah. Baghdad said it had sent military troops to restore order across southern Iraq, where protests have grown increasingly violent. Demonstrators have occupied buildings and bridges andhave clashed with security forces, who have used tear gas and live ammunition almost daily since protests began. 'A war zone' Amnesty International denounced the violence in Nasiriyah, calling it a bloodbath. "The scenes from Nasiriyah this morning more closely resemble a war zone than city streets and bridges. This brutal onslaught is just the latest in a long series of deadly events where Iraqi security forces meted out appalling violence against largely peaceful protesters,'' said Lynn Maalouf, the group's Middle East research director. .
