Despite a truce, Israeli raids on May 8 resulted in additional fatalities, including the killing of key Hezbollah commander Malek Balou in Beirut.

• •Tensions in the Strait of Hormuz remain high with repeated exchanges of fire between US and Iranian forces. On May 7 and 8, Iran launched missile, drone, and boat attacks against U.S. ships, which were intercepted, prompting warnings from President Trump and retaliatory strikes including US military actions against Iranian oil tankers. These engagements exacerbate the risk of escalation in a strategically critical maritime corridor.[France 24][France 24][The Hill][Al Jazeera]
• •The U.S. has dramatically increased economic and military pressure on Iran, including blocking over 70 tankers from entering or leaving Iranian ports to disrupt oil exports and sanctioning 10 individuals and entities linked to Iran’s Shahed drone supply network. These efforts aim to curtail Iran’s military capabilities and constrain its funding amid ongoing conflict.[Middle East Eye][Middle East Eye]
