The United States broadened its airstrike campaign against Iran early Friday, targeting additional bridges and apparently bringing down a tower at a key Iranian port. The latest attacks marked another escalation in a widening military operation.

Iranian officials said the strikes have killed dozens of people and wounded hundreds more. They also reported new casualties from the Friday attacks, indicating that the human toll continued to rise as the campaign expanded.

The reported damage at the port adds to concerns about disruption to major infrastructure, while the strikes on bridges suggest a focus on transportation links and strategic access points. The apparent collapse of a tower at such a significant port underscores the scale of the latest round of attacks.

With the United States extending its operations and Iranian authorities reporting increasing losses, the situation points to deepening instability and a sharper confrontation in the region.
