Iraqi officials say that a wave of deadly attacks across the country on August 16 killed at least 60 people.
Officials said the violence, one of the deadliest days since U.S. troops left in December 2011, hit 15 cities and left around 250 people injured.
The rise in violence comes as Muslims celebrate the end of the holy month of Ramadan with the festival of Eid.
Security officials said they had taken steps to ramp up security measures to protect crowds gathering in public places to celebrate the occasion over the weekend.
The attacks began early in the north of Iraq and ended with deadly bomb explosions near busy markets and restaurants before midnight.
There was no immediate claim of responsibility for the strikes, although officials blame Al-Qaeda's Iraqi affiliate, the Islamic State of Iraq.
