Four people died when a roadside bomb exploded in eastern Baghdad, while a car bomb in southern Baghdad killed at least one more person.

The attacks come one day after bombings across Baghdad killed at least 40 pilgrims and injured more than 100.

One million pilgrims are expected to gather at the Moussa al-Kadhim shrine on the final day of the festival.

There was no immediate claim of responsibility, but similar attacks in the past have been blamed on extremist Sunni groups.

The attacks come despite a vast security operation. Thousands of extra police and military officers have been drafted onto the streets of Baghdad and vehicle traffic has been restricted.
