The continued unrest in the Middle East could send gas prices soaring, but it could also have a different impact on Americans as well.

The State Department has issued a travel warning to any U.S. citizen going to or coming from Libya.

Channel 9 checked with Charlotte Douglas Airport and learned there are no increased security measures.

The warnings do not affect people traveling inside the U.S.

On Wednesday night, Channel 9 caught up with the former assistant director of the FBI, Chris Swecker, at the airport.

He said there are several unknowns that the government is looking into in Libya, including who exactly is responsible and if it is a work of terrorism.

He said people who do travel abroad need to be extremely cautious.

“When U.S. citizens are traveling abroad, they don’t enjoy a lot of protections.  They have contact at the embassy, but they need to pay attention to what the current conditions are,” Swecker said.

The airports in Libya are open and the State Department is encouraging U.S. citizens to leave the country.
