The US has put its military forces in Europe on alert in case they’re required to respond to a security crisis stemming from political unrest in Libya. Several teams of military personnel assigned to the US Africa Command and based in Stuttgart, Germany, have been put on notice and can reach parts of Libya quickly because they’re equipped with their own air transport, according to a US defense official.
 The quick reaction forces were created in the aftermath of the Sept. 11, 2012, attack on the U.S. mission in Benghazi. US and British embassies in the Libyan capital Tripoli withdrew some staff and issued travel warnings.
