>> The power struggle between Iraq's Shiite leaders is once again spilling blood on the streets of Bagdad. Put on the back burner to focus on the war on Islamic State, tensions are on the rise again. Followers of the influential cleric, Muqtada al-Sadr, took to the streets at the capital at the weekend.
A policeman was killed, 6 protesters, and 174 injured. Reuters's Maher Chmaytelli in Baghdad explains why the violence is happening now.>> They were demanding an overhaul of the body that oversees elections. And that's because we are going to see in the next few months and the provincial elections.
And next year we will have the crucial parliamentary elections that will decide who will be the next Prime Minister of Iraq.>> Protesters were attempting to cross the bridge that leads to the heavily fortified Green Zone, home to government buildings and embassies. Sadr says the electoral commission is favorable to his Shiite rival, former Prime Minister Nouri al-Maliki, a lawmaker he says is close to Iran and linked to corruption.
>> Unlike the other Shiite leaders who are backed by Iran, Sadr depends on rallying his troops under slogans, like reforms, battling corruption. Now that the battle seems to have been won against Islamic State, he thinks that the time has come for him to rally his troops and to start this other battle, which is against corruption.
>> Sadr has said protestors blood won't have been shed in vain, indicating this could be just the beginning of a long and difficult lead up to the elections.
