This is the second attack on an Iranian consulate in Iraq this month after an office in the Shia holy city of Karbala was targeted 
three weeks ago.

What's the background to the protests?

Mr Abdul Mahdi took office just over a year ago, promising reforms that have not materialised.

Young Iraqis angered by his failure to tackle high unemployment, endemic corruption and poor public services took to the 
streets of Baghdad for the first time at the beginning of October.

After the first wave of protests, which lasted six days and saw 149 civilians killed, Mr Abdul Mahdi promised to reshuffle his 
cabinet, cut the salaries of high-ranking officials, and announced schemes to reduce youth unemployment.
