Crisis Group expert Naysan Rafati says these tit-for-tat attacks on hydrocarbon infrastructure signal a new phase in the conflict, now entering its fourth week, as a global energy crisis looms and Gulf Arab states are increasingly caught in the crossfire, with Saudi Arabia warning of military action against Iran as these states’ patience wears thin. Crisis Group expert Renata Segura says the incident comes amid already high tensions between Havana and Washington, after the U.S. halted fuel imports coming into Cuba, exacerbating a severe energy crisis on the island, in hopes of pushing the Cuban authorities to negotiate an economic and political opening.
