The United States has initiated a military operation in Syria targeting the Islamic State group following a deadly attack in Palmyra that resulted in the deaths of three Americans. Defense Secretary Pete Hegseth announced that the operation aims to eliminate fighters, infrastructure, and weapons sites linked to the group. The action was described as a direct response to the recent attack on United States forces on December 13. The situation remains tense as the United States seeks to address ongoing security threats in the region.
