• Rezaei said US warships enforcing a blockade in the Strait of Hormuz could be targeted, stating they “can definitely be exposed to our missiles and we can destroy them.”
• He warned that any US ground invasion would trigger mass hostage-taking.
• “We would take thousands of hostages and then for each hostage we would get a billion dollars,” he said.
• Rezaei also described a potential US ground offensive as “great,” underlining Tehran’s aggressive posture.

US sharpens economic pressure with new sanctions

Washington continued its “maximum pressure” strategy by targeting Iran’s oil network.

• The US imposed sanctions on over two dozen individuals, companies and vessels linked to Mohammad Hossein Shamkhani.
• The network is accused of facilitating Iranian oil transport despite existing restrictions.
• Treasury Secretary Scott Bessent said the move was part of “Economic Fury.”
• “Treasury is moving aggressively… targeting regime elites like the Shamkhani family,” he said.

Israel aligns with US, expands military goals

Israel reiterated its strategic alignment with Washington and broadened its military objectives.

• Prime Minister Benjamin Netanyahu said Israel and the US share “identical” goals on Iran.

• Netanyahu also prioritised dismantling Hezbollah.
• “There are two central objectives: first, the dismantling of Hezbollah; second, a sustainable peace… achieved through strength.”
• Israel’s army chief ordered areas south of Lebanon’s Litani River to become a Hezbollah “kill zone.”

These moves indicate an expanding regional dimension of the conflict.

Diplomatic efforts continue despite setbacks

Even as hostilities persist, backchannel diplomacy remains active.

• The White House said talks with Iran are “productive and ongoing.”
• Press Secretary Karoline Leavitt indicated a second round of talks is likely.
• Islamabad is expected to host the next phase of discussions.
• China backed continued dialogue, supporting the “momentum of the ceasefire and peace talks.”

• The World Bank warned of a sharp rise in global hunger.

• The disruption in energy flows continues to impact global supply chains.
• Despite tensions, Wall Street indices closed at record highs on optimism over a possible deal.

• The US is combining economic sanctions with naval enforcement.
