The United States and Saudi Arabia launched airstrikes on Tuesday against Iran-backed militants in Iraq who had carried out more than two dozen drone attacks in recent days, the US military said. The strikes targeted groups aligned with Iran, following a period of relative calm. Separately, Iran's Revolutionary Guards struck and halted three oil tankers in the Strait of Hormuz early Wednesday, according to Iranian state media. The US military said it thwarted an "attempted surprise attack" by Iran after a days-long lull in fighting, though details of that incident were not provided. The developments come amid heightened tensions in the region. Israeli Prime Minister Benjamin Netanyahu, meanwhile, hailed an "excellent" meeting with US President Donald Trump, though the timing and content of that meeting were not specified. The US-led coalition continues operations against Iran-backed forces, which have escalated in recent months. The Iraqi government has not immediately commented on the strikes.
