Iran shifts tactics to intensify attacks on commercial shipping in the Strait of Hormuz, officials say
Question
Iran shifts tactics to intensify attacks on commercial shipping in the Strait of Hormuz, officials say
Direct answer
The reported increase in attacks raises the probability of further disruption to Gulf oil flows and higher maritime-risk premia, while the U.S. assertion of continued control limits the evidence for an outright closure.
