February 28, 2026 - U.S., Israel Conduct Strikes in Iran; Tehran Responds as Officials Monitor Escalation Risk

WASHINGTON — Military strikes carried out overnight by the United States and Israel inside Iran were followed by Iranian responses targeting U.S. positions across parts of the Middle East, according to officials and regional reports.

The operations mark one of the most direct exchanges involving the countries in recent years and have raised questions about whether the confrontation could expand beyond limited military action.

U.S. officials have not announced a formal declaration of war, which under the U.S. Constitution requires authorization from Congress. However, defense analysts note that active military exchanges are now underway, placing the situation in a legally and politically complex category often described as an armed conflict rather than a declared war.

Early assessments suggest current operations are focused on specific military objectives. Officials say the duration of strikes and whether additional regions or forces become involved will likely determine whether tensions stabilize or escalate further.

Governments across the region and international allies are closely monitoring developments as diplomatic and military responses continue to evolve.

The situation remains fluid.
