The United States military says it has killed or captured about 25 ISIL (ISIS) fighters in a wave of attacks over nine days in Syria. US Central Command (CENTCOM), which oversees the US military's Middle East operations, issued a statement on Tuesday marking the conclusion of the operations this month. The campaign followed the killing of two US soldiers and a civilian interpreter by an ISIL gunman in Syria on December 13 and widescale US strikes against the group six days later.
