BAGHDAD (Reuters) -- Iraqi Shi'ite factions on Saturday reached a deal to end fighting between militia and security forces in the Baghdad, officials said.

The violence has trapped the 2 million residents of Sadr City in a battle zone for around seven weeks and prompted aid workers to warn of a humanitarian crisis.
But it is unclear how much control the anti-American Sadr has over many of the militiamen who claim allegiance to him in Sadr City, stronghold of his Mehdi Army militia.
“Prime Minister Nuri al-Maliki has approved this agreement,” government spokesman Ali al-Dabbagh said. “The Iraqi government calls on all parties to commit to this deal, to be calm and show self-restraint.”
Dabbagh said the agreement called for militiamen to hand in their medium and heavy weapons.
Sadr spokesman Salah al-Ubaidi told Reuters he expected the pact to take effect either on Saturday night or Sunday with a total halt to all Iraqi military activity for four days.
