Iranian drones struck the U.S. embassy in Saudi Arabia on Saturday as the United States announced major combat operations against Iran [1].

The escalation marks a significant shift in regional hostilities, involving not only direct conflict between Washington and Tehran but also the covert participation of Gulf allies.

President Donald Trump said the U.S. is conducting "major combat operations" against Iran [1]. These actions follow a series of retaliatory strikes. Iran launched the drone attacks in response to previous U.S. and Israeli military actions [1].

The conflict has already taken a toll on American personnel. A Pentagon spokesperson said that about 140 U.S. service members have been wounded since the start of the war [3]. Of those, eight were severely wounded, and 108 have returned to duty [3].

Regional tensions expanded further on Sunday when a tanker was hit by unknown projectiles in waters north of Fujairah [2]. U.S. officials said that any Iranian interference in the Strait of Hormuz would be considered a breach of a ceasefire [2]. An Iranian MP also said that such interference would violate existing agreements [2].

While the U.S. leads the overt military response, other regional powers are operating in the shadows. Reports indicate that Saudi Arabia and the United Arab Emirates carried out covert attacks inside Iran [4]. These allies reportedly acted to deter Iran's regional ambitions, a strategy intended to weaken Tehran's influence across the Gulf.

These combined pressures—direct U.S. combat operations, covert Gulf strikes, and the targeting of diplomatic facilities—have pushed the region toward a state of open warfare. The strike on the embassy in Riyadh is particularly significant, as diplomatic missions are typically protected under international law.

"major combat operations" against Iran

The transition from proxy skirmishes to direct strikes on diplomatic soil and the coordination of covert operations by Saudi Arabia and the UAE suggest a concerted effort to dismantle Iranian regional influence. By targeting the U.S. embassy, Iran has crossed a traditional red line, providing the U.S. with the political justification for a broader military campaign. The focus on the Strait of Hormuz indicates that the global economy remains a primary lever in this conflict, as any prolonged disruption to shipping would trigger international pressure on both sides.
