In a statement, Saraya Salam called on its members to be fully alert to deal with any contingency. The statement did not explain the reasons for the request.

Earlier, Sadr Movement leader Muqtada al-Sadr had set November 15 for mass prayers in Baghdad's Medina.

He said several personalities would supervise the prayer, including the former deputy speaker of the Iraqi Parliament, Hakim Zamli.

On June 12, Iraqi PMs from Sadr's bloc resigned, and the speaker of the Parliament soon accepted their resignation. Sadr said that the move was to break the deadlock on the negotiations for forming the next Iraqi government. After almost a month, Sadr is again mobilizing the streets to his political ends.

Saraya al-Salam, previously known as the al-Mahdi Army, is a Shia faction under the umbrella of the Hashd al-Shaabi or Popular Mobilization forces founded by Sadr in 2003. They numbered between 10,000 and 50,000, according to independent claims.
