Why is the US attacking southern Iran’s civilian infrastructure?

The United States has escalated its military operations targeting Iran, prompting Tehran to accuse Washington of striking civilian infrastructure. Iranian officials report that railway stations and residential areas have sustained damage, alongside reports of attacks on bridges, water facilities, and food storage silos across southern Iranian provinces. US President Donald Trump indicated that energy sector targets would be addressed later in the campaign.

The escalation follows a month-old memorandum of understanding between Washington and Tehran that extended an April ceasefire and established a framework for negotiations. Both sides have since accused each other of violating the agreement. The renewed military activity coincides with growing tensions over the Strait of Hormuz, where Iran has threatened to block marine traffic following Oman's announcement of a new shipping corridor, while the United States has resumed a naval blockade of Iranian-bound vessels.

Military responses have extended across the region. Iran's military reported striking US aircraft at a military base in Bahrain, while Kuwait reported responding to missile and drone attacks. Air defence systems have been reactivated throughout the week across Bahrain, Kuwait, Oman, Qatar, the United Arab Emirates, and Jordan. The hardest-hit areas include Bandar Abbas, Iran's primary naval hub overlooking the Strait of Hormuz, where reports indicate casualties and damage to transportation infrastructure.

Analysts debate the strategic objectives behind the campaign, questioning whether strikes aim to degrade military capabilities, disrupt transport networks for potential ground operations, or apply economic and political pressure through infrastructure damage. The intensifying focus on civilian infrastructure has raised questions regarding compliance with international law and the risk of broader regional conflict.
