"Pressure Mounts on Biden as Iran Denies Involvement in Fatal Drone Attack on US Troops"

The killing of three U.S. troops by Iran-backed militants has intensified pressure on President Biden to take direct action against Iran, with options ranging from targeting Iranian forces inside or outside Iran to retaliating solely against the militants responsible. Republicans are calling for devastating military retaliation, while some Democrats express concern about the situation escalating into a regional war. Experts caution that striking Iran directly could lead to a major Middle East conflict, while others point to the limited impact of previous strikes against Iranian targets.
