US Department of Homeland Security at 'Heightened State of Vigilance' VOA News The U.S. Department of Homeland Security says it is operating at a " heightened state of vigilance" following the death of Islamic State leader Abu Bakr al-Baghdadi but there are no plans to issue an (National Terrorism Advisory System) alert unless "we develop specific or credible threat information" to share with the public. "Our security posture will remain agile, we will continue to mitigate and respond to the ever evolving threat landscape," the DHS said in a statement a day after President Donald Trump announced that U.S. military special forces operation in northwest Syria successfully targeted and "violently eliminated" Baghdadi. .
