A series of back-to-back powerful bomb explosions have claimed lives of at least 28 people across the capital Baghdad, security sources say. Iraqi security officials say at least nine people lost their lives in a car bomb attack targeting a checkpoint in Baghdad’s Shia neighborhood of Abu Dashir. This comes as a bomber rammed the car packed with explosives into the checkpoint. Nearly 20 people were also wounded in the fatal blast. Separately, four car bombs went off in various districts in Baghdad in less than ten minutes. Sources say at least 19 people were killed and more than 40 injured. Medics say the death toll is expected to rise as some of the seriously injured are said to be in critical condition. No group has yet claimed responsibility for the attacks, but Iraqi officials blame militants belonging to the ISIL terrorist group. The UN mission to Iraq said in a new report on Friday that at least 5,576 civilians were killed and 11,665 wounded in Iraq since January across the crisis-hit country. The developments come as rights groups say hundreds of thousands have fled their homes in Mosul, Iraq’s second-biggest city, fearing abductions and killings. The city has been under militant control since last month. Recently, several gruesome videos were released, purportedly showing members of the Takfiri ISIL group brutally killing Shia Muslims in drive-by shootings in Iraq. The terrorist group has links with Saudi intelligence services and is believed to be indirectly supported by the Israeli regime. Iraqi Prime Minister Nouri al-Maliki has blamed Saudi Arabia and Qatar for the security crisis and growing terrorism in his country, denouncing Riyadh as a major supporter of global terrorism.
