Baghdad ( CNN ) -- A wave of bombings left 51 people dead and more than 120 wounded Thursday in various Baghdad neighborhoods , including one in which angry residents later threw stones at security forces , the Interior Ministry said . At least 48 people were killed and 121 wounded when a parked car bomb detonated near a funeral tent in the predominantly Shiite neighborhood of Shula in northwestern Baghdad , an Interior Ministry official said . After the Shula bombing , people threw rocks at security forces , the official told CNN , and some people fired guns . Security forces withdrew until an Iraqi Army unit dispersed the crowds by shooting in the air and imposing a partial curfew in Shula , the official said . The gathering of the crowd reflects the growing frustration and anger against the government and security forces , especially by the country 's Shiites , who have come under intensive attacks in recent days . Iraq has witnessed in the past 10 days constant high-profile attacks , mainly targeting Shiites and security forces , that have claimed the lives of more than 200 people . Some 151 people were killed in the entire month of December . Attacks on security forces in Tikrit and Diyala were claimed by the Islamic State of Iraq , an umbrella group that includes al Qaeda in Iraq . There was no claim of responsibility for attacks on the Shiites . Officials have blamed al Qaeda and other Sunni extremist groups of carrying out these attacks in an attempt to reignite the sectarian war that gripped Iraq for years . Many Iraqis blame their security forces for not preventing these attacks and question the abilities of these forces to secure the country , especially as the U.S. military prepares for a complete troop withdrawal by the end of this year . Many have blamed the deteriorating security situation on politicians still not agreeing on key security posts that remain vacant in the government formed more than a month ago . Meanwhile , three people died in three other attacks in the Iraqi capital . A roadside bomb exploded next to a police patrol in southern Baghdad , killing a civilian and wounding seven people , including three police officers . In another attack in southeastern Baghdad , a roadside bomb exploded near a government convoy . It missed the convoy but killed one civilian and wounded three others . In central Baghdad , a roadside bomb exploded on a busy road , killing one civilian and wounding four . The blasts came after Wednesday night 's assassination of three government employees by gunmen using pistols equipped with silencers in three neighborhoods in Baghdad . Two of the three government employees worked at Iraq 's Ministry of Foreign Affairs and the third employee worked at the Ministry of Housing and Reconstruction .
