dubai, April 3 -- Iran fired more missiles at Israel and Gulf Arab states on Thursday, demonstrating Tehran's continued ability to strike its neighbours even as US President Donald Trump claimed the threat from the country was nearly eliminated. Iran's attacks on Gulf states along with its chokehold on the Strait of Hormuz have disrupted the world's energy supplies with effects far beyond the Middle East. That has proved to be Iran's greatest strategic advantage in the war. Britain held a call with nearly three dozen countries about how to reopen the strait once the fighting is over. Trump has insisted the strait can be taken by force - but said it is not up to the U.S. to do that. In an address to the American people Wednesday night, he encouraged countries that depend on oil from Hormuz to "build some delayed courage" and go "take it." Before the U.S. and Israel started the war on Feb. 28 with strikes on Iran, the waterway was open to traffic and 20% of all traded oil passed through it. Iran responded defiantly to Trump's speech, in which the American president claimed U.S. military action had been so decisive that "one of the most powerful countries" is "really no longer a threat." A spokesman for Iran's military, Lt. Col. Ebrahim Zolfaghari, insisted Thursday that Tehran maintains hidden stockpiles of arms, munitions and production facilities. He said facilities targeted so far by U.S. strikes are "insignificant." Just before Trump began his address - in which he said U.S. "core strategic objectives are nearing completion" - explosions were heard in Dubai as air defenses worked to intercept an Iranian missile barrage. Less than a half-hour after the president was done, Israel said its military was also working to intercept incoming missiles. Sirens sounded in Bahrain, home to the U.S. Navy's 5th Fleet, immediately after the speech. Attacks continued across Iran on Thursday, with strikes reported in multiple cities. Even amid the conflict, families went to a park in Tehran to play games and grill food to mark the last day of Iranian New Year, or Nowruz. In Lebanon - home to Iran-backed Hezbollah militants who are fighting Israel, which has launched a ground invasion - an Israeli strike killed four people in the south, the Health Ministry said. More than 1,900 people have been killed in Iran during the war, while 19 have been reported dead in Israel. More than two dozen people have died in Gulf states and the occupied West Bank, while 13 U.S. service members have been killed. More than 1,300 people have been killed and more than 1 million displaced in Lebanon. Ten Israeli soldiers have also died there. Iranian attacks on about two dozen commercial ships, and the threat of more, have halted nearly all traffic in the waterway that connects the Persian Gulf to the open ocean. Since March 1, traffic through the strait has dropped 94% over the same period last year, according to the Lloyds List Intelligence shipping data firm. Two ships are confirmed to have paid a fee, the firm said, while others were allowed through based on agreements with their home governments. Saudi Arabia piped about 1 billion barrels of oil away from the Strait of Hormuz in March, according to maritime data firm Kpler, while Iraq said Thursday that it had started to truck oil across Syria to avoid the strait. The 35 countries that spoke Thursday, including all G7 industrialized democracies except the U.S., as well as the United Arab Emirates and Bahrain, signed a declaration last month demanding Iran stop blocking the strait....
