Iran sharply criticized Gulf neighbors as the United States continued military strikes in the latest round of fighting between Washington and Tehran. The renewed confrontation appeared to deepen on Monday, with both sides reported to have carried out attacks.

The escalation also brought a rising human toll. According to the available details, the number of US deaths linked to the renewed fighting climbed to three, underscoring the growing cost of the crisis as military action continued.

Pressure was also building at sea. More ships reportedly came under attack in the Strait of Hormuz, a strategically vital waterway for global energy shipments and regional trade. Any increase in violence there is likely to heighten concern over maritime security and the risk of wider disruption.

A handout video released by US Central Command appeared to show American forces carrying out what the military described as precision strikes. With Iran denouncing regional neighbors and the US pressing ahead with operations, the standoff looked set to remain volatile.
