The intensified security measures come following intelligence reports suggesting the possibility of a terrorist attack in Karbala province.
A police spokesman in the holy city said intelligence services and security forces have taken precautionary measures and set up checkpoints to defuse any possible security threats against civilians.
Iraq has seen a surge in terrorist attacks on civilian targets in recent months, following victories achieved by the Arab country’s army and popular forces against the Daesh (ISIL or ISIS) terrorist group.
In the latest carnage, at least 39 people were killed and 57 more injured after a terrorist car bomb attack rocked a busy square in Sadr City, a Shia-populated suburban district of Baghdad on Monday.
Also, three bomb blasts killed 29 people across Baghdad on Saturday while an attack near the city of Najaf claimed the lives of seven policemen on Sunday. Daesh claimed responsibility for both assaults.
