If you recieve an email claiming the US has invaded Iran, do not follow the link in it. You may be tempted to see who is spreading lies, or worse, truth. However, it's merely the latest tactic of some spammer trying to get a virus on your PC. More info here.
This community is good at debunking BS rumors, so some of you may try to do that without realizing its a lie of a different sort.
I am aware this is short, but there's not much to say.
Possible subject lines to watch out for:
'Third World War has begun'
'20000 US Soldiers in Iran'
'US Army crossed Iran's borders'
