A series of car bombings and other attacks in Iraq, mostly targeting Shia majority - cities, have killed at least 59 people and injured scores more, according to security and hospital sources.All of the deadly incidents occurred in south and central Iraq on Sunday, a day after at least 27 people were killed in bombings and shootings across the country. In the city of Hillah, 95 kilometers south of Baghdad, 21 people were killed and 29 injured in two separate car bombings. The bomb attacks targeted an outdoor market in the city. In the nearby city of Iskandariyah, another car bombing occurred in a parking lot, killing four civilians and injuring nine others. In the holy city of Karbala, 80 kilometers south of Baghdad, another car bomb attack killed five and wounded 25 in an industrial area of the city. The bombing left burnt-out cars in front of a smashed row of workshops. In Kut, a city 160 kilometers southeast of Baghdad, a car bomb attack killed two and wounded 14 more. The bombing targeted a construction site and food stalls. In the towns of Suwayrah and Hafriyah located outside Kut, four separate car bombings killed seven people and injured 31 others. In Baghdad's northern Azamiyah neighborhood, a car bomb attack killed three and wounded eight people. The bombing apparently targeted a convoy of the head of Baghdad's provincial council, who escaped unhurt. Two more car bomb attacks struck the southern cities of Basra and Nasiriyah, killing eight civilians and wounding 26 people. In Baghdad's western suburb of Abu Ghraib, a bomb hit a police patrol, leaving two civilians dead and nine other people wounded. To the northeast of Baghdad, gunmen killed three farmers in the village of Abu Sayda. And police found the bodies of four men who were kidnapped from their house in Baghdad’s southern Youssifiyah suburb early on Sunday. They were killed with gunshots to the head. The incidents are the latest in a string of attacks across Iraq that have left more than 4,000 people dead since the beginning of April 2013. According to the United Nations, 1,057 Iraqis, including 928 civilians, were killed and another 2,326 were wounded in terrorist attacks throughout the country in July -- the deadliest month since 2008. And 804 Iraqis lost their lives in August in the deadly attacks, a third of which took place in Baghdad. No group has claimed responsibility for the Sunday attacks, but Iraqi security officials say the main suspects are militants linked to al-Qaeda because they conduct systematically organized waves of bombings to undermine the government. Earlier in the day, a former Iraqi national security advisor said Saudi Arabia is one of the major supporters of terrorism in the country. Mowaffak al-Rubaie said that all leaders of terrorist groups operating inside Iraq have come to the country from foreign states such as Saudi Arabia and Yemen.
