The United States has expanded its military campaign against Iran, with Tehran accusing Washington of targeting civilian infrastructure during a sixth consecutive night of airstrikes. Iranian officials say railway facilities, bridges, residential neighbourhoods, water systems and food storage sites have been damaged, raising fresh concerns over the objectives of the U.S. operation and its implications under international law.
The latest escalation follows comments by U.S. President Donald Trump that Washington would eventually target Iran’s energy sector, while fighting has intensified around the Strait of Hormuz, one of the world’s most strategically important shipping routes. Iran has also claimed it struck U.S. aircraft at a military base in Bahrain, while Gulf states reported responding to missile and drone threats. The renewed violence comes only a month after Washington and Tehran signed a memorandum aimed at extending a ceasefire and creating a framework for negotiations, with both sides now accusing each other of violating the agreement.
Civilian Infrastructure Increasingly in the Crosshairs
Much of the recent fighting has centred on southern Iran, particularly Hormozgan province and the port city of Bandar Abbas. Iranian authorities report damage to bridges, transportation links, communications infrastructure, airports, water facilities and hospitals, in addition to residential areas.
Officials say six bridges serving key transportation corridors around Bandar Abbas were struck, while damage was also reported at Iranshahr Airport and other civilian facilities. Health infrastructure has also been affected, with hundreds of patients evacuated from a hospital in Ahvaz after it became inoperable following nearby strikes.
Strategic Importance of Southern Iran
Military analysts say southern Iran has become a focal point because it hosts key naval installations and overlooks the Strait of Hormuz, through which a significant portion of global oil shipments passes.
Bandar Abbas is home to both Iran’s conventional navy and the naval arm of the Islamic Revolutionary Guard Corps (IRGC). Experts suggest attacks on bridges and transport networks could disrupt Iran’s ability to move military equipment and maintain operations along the Gulf coast.
Some analysts also argue that targeting infrastructure increases economic pressure on Tehran while weakening military logistics, although others caution that the expanding target list has prompted speculation about broader strategic objectives.
Debate Over International Law
Iran has condemned the strikes as violations of international humanitarian law, accusing the United States of deliberately attacking civilian infrastructure and committing war crimes.
Under the Geneva Conventions, civilian infrastructure is protected unless it is being used for military purposes. Legal experts note that governments often justify attacks by classifying facilities as “dual-use” infrastructure, although such claims are frequently scrutinized after conflicts end. Whether specific strikes comply with international law will depend on evidence regarding the military value of the targeted sites.
Pressure or Preparation?
Analysts remain divided over Washington’s broader strategy. Some believe the campaign is intended to weaken Iran’s ability to threaten shipping in the Strait of Hormuz and force Tehran back to negotiations. Others argue the widening scope of attacks could be laying the groundwork for future military operations, though many experts consider a ground invasion unlikely due to the significant risks involved.
Despite differing assessments, analysts agree that attacks on civilian infrastructure are likely to increase pressure on the Iranian government while also risking greater humanitarian consequences and further escalation of the conflict.
