The United States has broadened its sanctions regime against Iran's oil sector, specifically targeting the network associated with Ali Shamkhani.
The move comes in response to recent attacks in the Strait of Hormuz, signaling a tightening of economic pressure on Tehran's energy exports.
This development adds to a significant existing sanctions framework.
The US has previously imposed restrictions on more than 200 individuals, entities, and vessels operating under Iran's shipping network.
Those earlier measures aimed to disrupt the country's oil exports and increase economic pressure on the regime.
The new actions specifically focus on the Shamkhani network, indicating a targeted escalation within the broader sanctions strategy.
