The first attack took place when a suicide bomber on Thursday evening detonated his explosives among Shia pilgrims in the town of Al-Batthaa.
About 36 people were killed and 72 others injured in this deadly attack. An Iraqi army officer and two soldiers who were guarding the procession were among the dead.
The pilgrims were walking on a main road leading to the holy Shia city of Karbala, some 110 km south of Baghdad, to observe the religious ritual of Arbaeen.
The ritual marks the end of the 40-day mourning for Imam Hussein, Muhammad\\\’s grandson who was killed at the battle of Karbala in 680 A.D.
Earlier in the day, at least 24 people were killed in bombings in the Iraqi capital.

Two more bombs were detonated in quick succession at a busy intersection near the al-Sadr hospital in Sadr, the interior ministry said. Dozens of people were injured in the blasts.
Explosions also took place in northern Baghdad.
