Tensions in the region have escalated following a series of military engagements between the United States and Iran. On Sunday, Iranian Parliament Speaker Mohammad Baqer Qalibaf issued a public warning, stating that Iran would respond to any future aggression with a "faster, heavier, and more painful" reaction. Qalibaf explicitly stated that the era of "proportionate responses" has concluded, suggesting a shift in Tehran's military doctrine regarding how it handles perceived threats to its national interests.

This rhetoric follows reports that the United States military recently conducted strikes against Iranian oil tankers. According to the BBC, these US actions were carried out in retaliation for earlier Iranian attacks directed at American warships operating in the region. While both sources confirm the exchange of threats and the recent military activity, they differ in their focus. The Tehran Times frames the warning as a defensive posture against "aggression" toward national interests, whereas the BBC focuses on the sequence of retaliatory actions between the two nations, contextualizing the Iranian threat as a direct response to the US strikes on tankers.
