Dubai: Falling debris from intercepted missiles injured four people in Dubai early Tuesday, as regional tensions escalated following fresh Iranian strikes and widening conflict across the Gulf.

Authorities said the debris sparked a fire in an abandoned house in the Al Badaa area, with emergency services quickly containing the blaze. The incident came amid intensified hostilities, including a reported Iranian attack on a Kuwaiti oil tanker at Dubai Port.

Iran launched new missile attacks while vowing defiance against Donald Trump, who warned of potential strikes on key Iranian infrastructure, including the Kharg Island oil export hub, if Tehran fails to agree to end the war.

Meanwhile, Benjamin Netanyahu said Israel had achieved more than half of its military objectives, though he declined to provide a timeline for the ongoing operation.

The conflict has begun to spill across the region. Saudi Arabia said it intercepted eight ballistic missiles, while Iran’s Foreign Minister Abbas Araghchi urged Riyadh to expel US forces, despite calling the kingdom “brotherly”.

In a further escalation, Iranian lawmakers moved to impose tolls on vessels passing through the Strait of Hormuz—a critical route for global oil shipments—and proposed banning US and Israeli ships entirely.

US Secretary of State Marco Rubio condemned the plan, warning it would set a dangerous precedent for control over international waterways.

As tensions rise, analysts warn that threats to target civilian infrastructure could violate international humanitarian law, raising fears of a broader and more destructive regional conflict.
