US embassy staff fled the country last night.
US-Iraq relations have soured since US bombed a PMF (Popular Mobilisation Force) group who they say was behind a bombing last Friday that killed a US contractor. The PMF denies the charge & is one of several militia groups in Iraq that act as a frontline defense against ISIS...US bombed ISIS' main enemy in Iraq!
Here's some background to the situation:
Note: the embassy is inside the greenzone which has Iraqi forces manning the checkpoints. They did not stop the demonstration, this is telling (shows Iraq govt support).
