An Iraqi demonstrator gestures with the v-sign for victory during a demonstration against state corruption, failing public services, and unemployment, in the Iraqi capital Baghdad on October 5, 2019. Renewed protests took place under live fire in Iraq's capital and the country's south Saturday as the government struggled to agree a response to days of rallies that have left nearly 100 dead. The largely spontaneous gatherings of demonstrators -- whose demands have evolved since they began on Tuesday from employment and better services to fundamental government change -- have swelled despite an internet blackout and overtures by the country's elite. Hours after a curfew in Baghdad was lifted on Saturday morning, dozens of protesters rallied around the oil ministry in the capital, facing live rounds fired in their direction, an AFP photographer said.
