Is this something that actually just happened, or is it a retelling of the last time contractors were murdered and their bodies desecrated?
If it's something new, we do the eqiuvalent of "nuking the planet from orbit... It's the only way to be sure."
Seriously, if this is something new, we need to get the friendlies out of the city, surrounding it and giving them 24 houre. Then raize it to the ground, killing everyone left there.

It is new but similar.
B.S. - do it, do it right, do it right now!
