Around 55 people were killed in Iraq in attacks on Saturday that targeted a Shi'ite Muslim gathering, a police check-point and the family of a Sunni paramilitary leader opposed to Islamic State, according to security and medical sources, Reuters reported.
The escalation comes as Iraqi forces are getting ready to launch an offensive to take back Mosul, the last Iraqi city still under control of Islamic State, in northern Iraq.
The heaviest toll was caused by a suicide bomber who detonated an explosive vest in the middle of a Shi'ite gathering in Baghdad, killing at least 41 people and wounding 33.
