On Sunday morning, signs were abundant that the war that began a day earlier with US and Israeli attacks on the Islamic Republic was spreading. Sirens sounded as far as Tel Aviv, missile defenses intercepted incoming Iranian projectiles in Qatar and Bahrain, and there were reports of attacks on Dubai’s main airport, the world’s busiest aviation hub. The Strait of Hormuz, which links the Persian Gulf to the open sea, was described by Iran’s Tasnim news agency as being practically shut, with oil and gas tankers increasingly avoiding the waterway.
