Unclear Situation in Baghdad

There is a strict curfew in Baghdad:

During most previous days of curfew, vehicles and pedestrians were occasionally seen on the streets but this is not the case today. At least that's what I heard from people who tried to move around for shopping or other business. All, whether driving or on foot, were ordered to go home.

Omar:

[...] there's a rumor in Baghdad that al-Qaeda was planning to launch a major offensive in Baghdad and takeover wide sectors of the city. The rumor that was heard for the first time several days ago speaks of 3,000 al-Qeada fighters who have entered the city for that reason.

Dang.
