Summary

The US military struck three Iranian oil tankers on Saturday in response to an alleged missile attack on American warships, further escalating tensions in the region. Two of the tankers were "permanently disabled" and one was destroyed. The US claims the vessels were part of a shadow network financing Iran's Revolutionary Guards and proxy groups. The incident is the latest development in the ongoing conflict between the US and Iran, which has seen both sides engage in strikes after about a month of relative calm.
