US forces began a further round of strikes on Iranian military targets at 18:45 Eastern time on July 23, US Central Command said, describing it as the 13th consecutive night of attacks.

The tempo of the campaign now matches the strain on the Pentagon's own resources, with Defense Secretary Pete Hegseth putting costs at $37.5bn and the department seeking an immediate $67bn from Congress. The strikes came hours after the House voted 214-208 to direct the withdrawal of US forces from hostilities.

CENTCOM said the operations were intended to hold Iran accountable and reduce threats from the Islamic Revolutionary Guard Corps to commercial shipping.

Points around Ahvaz in Khuzestan province came under missile attack shortly after midnight local time on July 24, Vali Allah Hayati, deputy governor for security and law enforcement affairs, told IRNA. He said field assessments were under way and that further information on damage would follow.

Several explosions were heard at Bandar Abbas about 15 minutes later, Fars reported. The agency said the blasts came from the west of the city and the Allah-o Akbar hills, an area struck on multiple previous occasions.

Bandar Abbas is the base of the Iranian navy's southern fleet and the country's largest container port, sitting on the northern shore of the Strait of Hormuz. The waterway has been effectively closed to unauthorised traffic since Iran took control of transits in late February.
