Threats from terrorist groups prompted the U.S. State Department to issue a nationwide travel alert covering the next three months, said Bulloch County Public Safety Director Ted Wynn. "At present, this travel alert goes into February of next year," Wynn said. Terrorist groups such as ISIS, or the Islamic State of Iraq and Syria, and ISIL, or the Islamic State of Iraq and the Levant, which refer to the same group, as well as al-Qa'ida and Boko Haram have claimed responsibility for many terrorist attacks worldwide and are issuing more threats of violence, according to www.travel.state.gov.
