Saudi Arabia said Wednesday it had intercepted a wave of seven drones heading towards a strategic oil field, as Iran renewed fire on its Gulf neighbours and their energy infrastructure.

Iran’s central military command, Khatam al-Anbiya, warned it will target economic centers and banks linked to the United States and Israel across the region after overnight strikes.

Drones fell near Dubai airport, injuring four people, while ships were hit in or near the Strait of Hormuz on Wednesday as Iran kept up its campaign disrupting oil markets and air and maritime traffic.

Iran has begun laying mines in the Strait of Hormuz, the world’s most important energy chokepoint that carries about one-fifth of all crude oil, according to two people familiar with US intelligence reporting on the issue.

Pakistan's Prime Minister Shehbaz Sharif on Monday unveiled a raft of austerity measures designed to save fuel, as oil prices soar due to the US-Israeli war on Iran.

Iran vowed on Tuesday that not one litre of oil would be exported from the Gulf while its war with the United States and Israel continues, in a stark rebuke to President Donald Trump's boast that the conflict was all but over.

Speaking at a Republican conference, Trump claimed the United States sank 46 Iranian naval vessels in just days and warned Iran that any attempt to block oil shipments through the Strait of Hormuz would trigger a much stronger U response.

Iran launched new attacks on Tuesday at Israel and Gulf Arab countries as it kept up pressure on the Middle East in a war that has impacted the region and beyond, sent oil prices surging and stunned global economies.
