AFP, MOSUL, IraqIraqis across the country yesterday marched to mourn protesters killed in anti-government rallies, even turning out in Sunni areas where people were previously too afraid to join in. After a spike in deaths this week raised the toll to more than 420 killed, Iraqi Prime Minister Adel Abdel Mahdi on Friday said he would submit his resignation to parliament. However, after a spike in violence days ago left nearly 70 people dead across three cities, Iraqis in nearly all provinces turned out in solidarity. Eight other Shiite-majority provinces have announced yesterday a mourning day during which government offices would remain shut. The protest hotspot is the birthplace of Abdel Mahdi, who came to power just a year ago based on a shaky alliance between rival parties.
