A second deadly explosion has struck Baghdad, killing at least seven people and wounding 30, according to security sources and witnesses.
The blast at Al-Shahada Bridge came hours after a suicide car bomber in the Karrada district killed at least 15 people and wounded dozens who were gathered at an ice cream shop.
The second blast on Tuesday was also a car bomb attack, security officials said.
Ibrahim Al-Zararee, writing on Twitter, said he was "seconds away" from the attack.
"Yesterday I was a few hours away from the site of the explosion [in Karrada]. Today I was few seconds away from it," he said. "The explosion today was near the General Retirement Department. A walking distance from the famous Mutanabi Street."
Video posted to social media showed plumes of black smoke rising from a building.
The Islamic State of Iraq and the Levant (ISIL, also known as ISIS), claimed responsibilty for the first attack, which came as the Muslim holy month of Ramadan got under way.
