ISIS is being challenged by Sgt. Dakota Meyer, a U.S. Marine for 4 years and Medal of Honour recipient, on social media to come and "show up at his door." Support for Meyer has been growing as he threatened ISIS militants on Twitter amid reports of the extremist group targeting U.S. soldiers.

Meyer told ABC that he doesn't want to live in fear because of ISIS threats. He said he refused to change his life out of worrying that something could happen to him. It would only mean "terrorism is winning." The26-year-old said he didn't want the "radical bullies" to change the way he lives.

The FBI has recently issued a warning to U.S. soldiers to review the content of their social media accounts for anything that might attract unwanted attention. Members of the military were told to check for personal details that ISIS may use against them. The FBI and the Department of Homeland Security has acquired intelligence reports that ISIS is planning to recruit people who are living in the U.S. to attack soldiers in their hometowns.

Meyer's comments and taunts of ISIS have gone viral in Twitter and Facebook. He called ISIS militants "cowards" and encouraged his followers to post images of the American flag on his social media page. He said he was tired of the warnings and added that it should be the FBI who should give ISIS a warning. Meyer made it clear that he doesn't want ISIS to attack the military and his challenge to the group only applied to himself.

In response to the growing ISIS threat on American soil, U.S. Senator Rand Paul, a Republican from Kentucky, has introduced a measure to declare war against ISIS since President Barack Obama has no authority to launch a war against the group. In an NPR report, Rand said that Congress has the duty to act and authorise Mr Obama's declaration of war last September. In earlier reports, administration officials believe the president could order a military action against ISIS based on the 2001 Authorisation for Use of Military Force passed by Congress.

Meanwhile, U.S. officials are closely monitoring recently developed ISIS training camps in Libya. According to Fox News, the U.S. Africa Command head Gen. David Rodriguez told a Pentagon briefing that the training camps are composed of local militants attracting attention by associating with ISIS. He said it was yet to be determined if they pose a serious threat since there is currently a lack of information.
