US military has resumed its air strikes against Iran in broad daylight on Wednesday, as Washington said it was intensifying its campaign aimed at limiting Tehran’s ability to threaten commercial shipping in the Strait of Hormuz.

According to US Central Command (CENTCOM), a new 90-minute wave of precision strikes against Iranian targets on Wednesday morning targeted coastal defence systems as well as cruise missile storage and launch sites on Greater Tunb Island.

CENTCOM said the strikes were intended to further reduce Iran’s ability to attack commercial vessels passing through the strategic waterway.

The operation marks a further escalation in the US military campaign against Iran, following Tehran's repeated attacks on ships in the Persian Gulf.

Iran had struck at least seven commercial vessels over the past week, according to CENTCOM.
