The threat came as Iranian missiles struck two southern Israeli cities overnight, injuring dozens and shattering apartment buildings. The developments signal a dangerous new phase in the four-week-old conflict, with both sides now openly threatening critical civilian infrastructure.

Tehran stated that energy and oil sites across the entire region would become legitimate targets in the event of US strikes on Iranian energy infrastructure. The threat implicitly encompasses oil facilities in Saudi Arabia, the UAE, Kuwait and other Gulf states, most of which host US military installations.

Israeli settlers simultaneously carried out coordinated attacks across the occupied West Bank, setting homes and vehicles on fire and wounding several Palestinians in what witnesses described as organised raids on multiple communities. The violence was reported across at least half a dozen locations overnight.

The escalation cycle now involves direct threats to the energy infrastructure that the global economy depends on, with both Washington and Tehran drawing red lines around facilities whose destruction could trigger a worldwide economic crisis far exceeding the current oil shock.
