A few days after jihadists attacked the comic sketch exhibition in Texas, the US is raising its security levels on bases on US soil.

According to the FBI, the jihadist threat led to said increase in security, since there are hundreds of jihadist supporters on social media operating in the US.

At the same time, he added that there is a great worry that ISIS will focus on armed forces personnel across the country.

Said increase in security happened more than ten years ago, after the 9/11 attacks.
