(WASHINGTON, D.C.) - Americans are being warned to stay alert as we approach the July 4th holiday. This comes after some violent killings Friday: in France, Kuwait and on a Tunisian beach packed with vacationers.
ISIS claimed responsibility for the Tunisian attack that killed 38 people, dozens more injured.
A bulletin was sent to 18,000 law enforcement agencies to be on high alert heading into the holiday weekend for possible ISIS-inspired attacks.
Officials are also warning Americans: "If you see something, say something."
"Enjoy the Fourth of July parades, but remain vigilant during these celebrations," said Rep. Michael McCaul from Texas, the Homeland Security Committee Chairman.
One reason officials are so concerned is because of the way ISIS has used social media in an unprecedented way to bring in new recruits.
