Tensions between the USA and Iran have escalated further as Donald Trump warned that the US could target Iranian bridges and power plants if Tehran does not return to negotiations. His remarks came as both countries exchanged fresh military strikes and the USA resumed its blockade of Iranian ports. American forces said they had struck military targets linked to threats against shipping in the Strait of Hormuz, while Iran reported attacks on US military sites in neighbouring countries and defended its actions in the strategic waterway. The renewed confrontation has disrupted commercial shipping and contributed to rising global oil prices. International concern has also focused on the protection of civilians and civilian infrastructure, with human rights officials warning that deliberate attacks on essential civilian facilities would violate international humanitarian law. Diplomatic efforts remain uncertain as both sides continue to exchange threats while rejecting each other’s demands.
