Heavy security presence deployed in Iran's Zahedan following armed clashes, according to Iran International

Zahedan, the capital of Sistan-Baluchestan near the Pakistan and Afghanistan borders, has been one of the most recurrent flashpoints of internal unrest in Iran, with past episodes there involving clashes between security forces, Baloch armed groups, and protesters, and heavy deployments of this kind have typically signalled an effort to contain rather than a widening conflict. Sourcing from Iran International, an opposition-leaning outlet, warrants the usual caution: such reports often precede official acknowledgment and the scale can be contested until corroborated by state media or independent channels. For crude markets, the established pattern is that domestic Iranian unrest of this kind has not historically tightened supply on its own; the transmission channel that matters is escalation toward export infrastructure, Gulf shipping, or a broader state response, none of which is indicated here. Worth watching is whether the clashes are attributed to insurgent activity, which has been endemic to the province, or to protest-related unrest, since the latter has on past occasions spread across provinces. Follow-ons are any official Iranian confirmation, internet restrictions in the region, and casualty figures, which have tended to determine whether such episodes persist in the tape.
