Dubai. US President Donald Trump openly mused about seizing Iran’s Kharg Island oil terminal in the Persian Gulf as the United States and Israel kept up their attacks Monday on the Islamic Republic, even as there were signs of progress in nascent ceasefire talks. Tehran, meanwhile, struck a key water and electrical plant in hard-hit Kuwait, part of its ongoing campaign targeting the Gulf Arab states.

As a diplomatic effort being facilitated by Pakistan toward ending the war moved ahead, Trump said Iran had agreed to allow 20 oil tankers through the Strait of Hormuz starting Monday as “a sign of respect.” At the same time, with 2,500 US Marines now in the region and a similarly sized contingent on its way, he raised the idea of taking Iran's Kharg Island.

“Maybe we take Kharg Island, maybe we don't,” he told the Financial Times in an interview published early Monday. “We have a lot of options.”

Iran Launches Attacks on Israel and Hits More Infrastructure Targets in Gulf States
Sirens sounded at dawn near Israel's main nuclear research center, a part of the country that has been targeted repeatedly in recent days. Israel's military also said it had taken out two drones launched from Yemen, where the Iranian-backed Houthis entered the war on Saturday with their first missile attack.

Iran kept up the pressure on its Gulf Arab neighbors, as Saudi Arabia intercepted five missiles targeting its oil-rich Eastern Province, Bahrain sounded a missile alert, and a fireball erupted over Dubai as an incoming missile was taken out by defenses.

In Kuwait, an Iranian attack hit a power and desalination plant, killing one worker and injuring 10 soldiers, the state-run KUNA news agency reported.

Desalination plants remain crucial to water supplies in the Gulf Arab states, and an Iranian attack previously damaged a desalination plant in Bahrain during the war. The facilities are typically paired with power plants, because of the large amount of energy required to remove salt from the water to make it drinkable.

Israel’s military launched a new wave of attacks on Iran, saying it was striking “military infrastructure” across Tehran. Iranian media also reported that one of the facilities of Tabriz Petrochemical was struck in a northern province of the country. They said no hazardous materials had been released.

In Lebanon, which Israel has invaded by ground, an Indonesian peacekeeper was killed, and three others were wounded when a projectile exploded near a village in the south.

Over the weekend, Israeli Prime Minister Benjamin Netanyahu said the military will widen its invasion, expanding the “existing security strip” in that country’s south as it targets the Iran-linked Hezbollah militia.

Iran's attacks on the energy infrastructure of the region and its stranglehold on the Strait of Hormuz, through which a fifth of the world's oil is shipped in peacetime, have sent oil prices skyrocketing and given rise to growing concerns about a global energy crisis.

In early trading, the spot price of Brent crude oil, the international standard, was around $115, up nearly 60% from when the US and Israel started the war with attacks on Iran on Feb. 28.
