It seems to be getting worse in Paris,

at least from the looks of this:
PARIS - Dozens of hooded attackers opened fire on police this weekend, wounding four officers, France's interior minister said.

Michele Alliot-Marie called the Sunday afternoon attack an "ambush," saying that about 30 people, some of them armed, were waiting for the officers in the southern Paris suburb of Grigny. The officers were responding to a call about vandalism of a local bakery.

'Ambush' is the right word. Planned, prepared and- I don't doubt- more of the same in the making.
