Saudi Arabia has summoned Iran’s ambassador in Riyadh to issue a formal protest following a series of drone and missile attacks that the kingdom says targeted its territory and critical infrastructure, marking a sharp diplomatic escalation amid intensifying regional hostilities.

According to Saudi officials, the foreign ministry delivered a strong message condemning what it described as violations of sovereignty and threats to civilian and energy facilities.

The summons comes in the wake of intercepted aerial threats near strategic oil installations, including facilities central to the kingdom’s export capacity.

Riyadh has reiterated that it holds Tehran responsible for actions carried out directly or through allied armed groups, warning that continued aggression risks widening the conflict across the Gulf.

Officials stressed that the kingdom reserves the right to defend its territory and citizens in accordance with international law.

The diplomatic move follows heightened military readiness across Saudi defence forces after recent incidents involving unmanned aerial vehicles and projectiles.

Authorities say air defence systems successfully neutralised several threats before they could inflict significant damage, though falling debris in some cases caused limited disruption.

Iran has previously denied direct involvement in attacks attributed to it or to groups aligned with it, framing such accusations as politically motivated.

However, Saudi officials maintain that the pattern of strikes forms part of a broader escalation that demands accountability.

Energy markets have reacted nervously to the developments, given Saudi Arabia’s role as one of the world’s leading oil exporters and the strategic importance of its eastern province infrastructure.

Analysts note that any sustained targeting of Gulf energy facilities could have far-reaching economic consequences.

The summoning of the ambassador underscores a deteriorating diplomatic climate at a time when regional actors face mounting pressure to prevent further military spillover.

While Saudi Arabia has signalled its preference for stability and de-escalation, the latest move reflects a clear warning that continued attacks will carry diplomatic and potentially broader consequences.
