This was also going on in Iraq about a year ago.
From the posted article:
The MoD confirmed that families of troops in Iraq have also suffered from “nuisance calls” in the past year.
So it seems that once again, similar tactics move from one theater of battle to another....perhaps because it's the same enemy? The Leftists who say that "we should have stayed in Afghanistan because Iraq has nothing to do with it" don't see the common puppet-master behind the screen.....Iran?
