Yes. Except the government hasn't yet determined how long to run this one. It could last as late as Thursday, depending on how the security situation is assessed. Almost 60 innocent people lost their lives to terrorists in Baghdad yesterday.
Back in the wilder days, curfews were commonplace and there was even a standard Friday curfew every week for a while in '06.
Now, they're much more rare, but still necessary on occasion.
So this is an Iraqi-government “curfew?” And the Iraqi government will determine when to lift it?
