US intelligence agencies are investigating whether Russia provided targeting information or advanced drone technology to Iran during recent attacks on CIA facilities in the Gulf region.

The probe represents a significant escalation in the attribution of the strikes, which have already heightened tensions across the Middle East.

Four people familiar with the matter told Reuters that the investigation is underway, though no formal accusations have been made public.

The potential involvement of Moscow adds a complex layer to the ongoing conflict, suggesting that the attacks may have been supported by external powers beyond Iran's immediate sphere of influence.

This development follows a sharp escalation in which Iranian armed forces launched strikes on US military infrastructure in neighboring Gulf states.

The attacks were described as a direct response to recent US actions in the region, marking a dangerous new phase in the conflict.
