The U.S. Department of State issued a new travel warning Tuesday, advising "U.S. citizens currently in Libya depart immediately."
"The security situation in Libya remains unpredictable and unstable. The Libyan government has not been able to adequately build its military and police forces and improve security following the 2011 revolution. Many military-grade weapons remain in the hands of private individuals, including antiaircraft weapons that may be used against civilian aviation. ...
"In addition to the threat of crime, various groups have called for attacks against U.S. citizens and U.S. interests in Libya. Extremist groups in Libya have made several specific threats this year against U.S. government officials, citizens, and interests in Libya. Because of the presumption that foreigners, especially U.S. citizens, in Libya may be associated with the U.S. government or U.S. NGOs, travelers should be aware that they may be targeted for kidnapping, violent attacks, or death.
"U.S. citizens currently in Libya should exercise extreme caution and depart immediately."
