A car bomb claimed by the self-styled Islamic State terrorist group in a Shia Muslim district of Baghdad killed at least 50 people and wounded more than 60 others on Wednesday, Iraqi police and hospital sources said.
The SUV packed with explosives went off near a beauty salon in a bustling market at rush hour in Sadr City. Most of the victims were women and many of the wounded are in critical condition, the sources said, Reuters reported.
Amaq news agency, which supports IS, said a suicide bomber had targeted Shia militia fighters.
The ultra-hardline extremist group, which considers Shias apostates, claimed a twin suicide bombing in Sadr City in February that killed 70 people.
Security has gradually improved in Baghdad, which was the target of daily bombings a decade ago, but violence directed against both the security forces and civilians is still frequent and large blasts sometimes set off reprisal attacks.
