Few hours after the US launched devastating 'targeted airstrikes' on Islamist militants ISIS, who have seized many towns in Iraq and are killing non-Muslims, the Jihadist group has vowed to 'raise their flag at the White House". 

Some members and supporters of the terrorist group took to twitter yesterday to threaten the US with war. They tweeted gruesome pics of dead American soldiers from the previous war in the country, U.S. marines hung from bridges in Fallujah, decapitated men, human heads on spikes, and pics from the deadly attack on US on 9/11. They also vowed to blow up US embassies.

With the hashtag #AmessagefromISIStoUS, over 2000 threatening tweets were posted on Twitter. One member wrote "This is a message is for every American citizen. You are the target of every Muslim in the world wherever you are.'. Another one wrote "ready to cut your heads dear Americans O sons of bitches. Come quickly.'

Reacting, a US military official said ISIS is yet to know the full power of the US military force and will soon find out what they are capable of.
