Iran’s top diplomat on Friday headed to Pakistan, where officials have been trying to get the United States and Iran to convene for a second round of ceasefire negotiations . The trip comes as much of the world is on edge over a war that has snarled crucial energy exports through the Strait of Hormuz , clouded the global economic picture, and left thousands dead across the Middle East. Foreign Minister Abbas Araghchi wrote on X that he was on his way to Pakistan, Oman, and Russia on a trip focused on “bilateral matters and regional developments.” The White House did not immediately respond to questions about Araghchi’s trip and whether a U.S. delegation would also travel to Pakistan. Islamabad has sought to reinject momentum into the negotiations between Iran and the United States, which did not resume this week as had been expected. Trump extends the Jones Act waiver for 90 days Separately, on Friday, the White House said President Donald Trump issued a 90-day extension to the Jones Act waiver , making it easier for non-American vessels to transport oil and natural gas. Trump first announced a 60-day waiver in March in a move intended to stabilize energy prices and ease oil and gas shipments to the U.S. following the effective closure of the Strait of Hormuz. “New data compiled since the initial waiver was issued revealed that significantly more supply was able to reach U.S. ports faster,” the White House post on social media said. The price of  Brent crude oil,  the international standard, retreated on the news, vacillating between $103 a barrel and more than $107 — still early 50% higher than where it was on Feb. 28, when the Iran war began. The squeeze on shipments through the strait has rippled through global maritime trade flows, including  through the Panama Canal  nearly halfway around the world. Pakistan forges ahead with diplomatic efforts Pakistan has been trying to get U.S. and Iranian officials back to the table after Trump this week announced an indefinite  extension of the ceasefire with Iran , honoring Islamabad’s request for more time for diplomatic outreach. That  hasn’t lowered tensions  in the  strait , a strategic waterway through which a fifth of the world’s oil and natural gas is shipped during peacetime. Iran has kept its stranglehold on traffic through the strait, attacking three ships earlier this week, while the U.S. is maintaining a blockade on Iranian ports and Trump has ordered the military to  “shoot and kill” small boats  that could be placing mines. “Iran has an important choice, a chance to make a deal, a good deal, a wise deal,” U.S. Defense Secretary  Pete Hegseth  told reporters on Friday. He said a second U.S. aircraft carrier will join the blockade in a few days. Washington already has three aircraft carriers in the region; the USS George H.W. Bush in the Indian Ocean; the USS Abraham Lincoln in the Arabian Sea; and the USS Gerald R. Ford in the Red Sea. It is the first time since 2003 that three American carriers have been operating in the region simultaneously. The force includes 200 aircraft and 15,000 sailors and Marines, U.S. Central Command said. A growing toll even as ceasefires hold Since the war began, at least 3,375 people have been killed in Iran, and more than 2,490 people in Lebanon, where new fighting between Israel and the Iran-backed militant group Hezbollah broke out two days after the war started, according to authorities. Additionally, 23 people have died in Israel and more than a dozen in Gulf Arab states. Fifteen Israeli soldiers in Lebanon and 13 U.S. service members throughout the region have been killed. The U.N. peacekeeping force in southern Lebanon has also sustained casualties. UNIFIL said Friday that an Indonesian peacekeeper died of wounds sustained in an attack on his base on March 29, raising to six — four Indonesians and two French — the number of force members killed since the war erupted. Tensions linger in Lebanon despite extended truce The situation in Lebanon remained tense a day after Trump announced Israel and Lebanon had agreed to extend a ceasefire  between Israel and Hezbollah  by three weeks. Hezbollah has not participated in the diplomacy brokered by Washington. Israeli Prime Minister Benjamin Netanyahu, in a video statement released by his office on Friday, hailed “a process to achieve a historic peace between Israel and Lebanon.” Earlier, the Israeli army asked residents of the southern Lebanese village of Deir Aames to evacuate, saying Hezbollah was using the village to launch attacks against Israel. Israel’s military said it downed a drone over Lebanon following the launch of a small surface-to-air missile by Hezbollah. The militant group, meanwhile, said it shot down an Israeli drone with a surface-to-air missile over the outskirts of the southern port city of Tyre. —Munir Ahmed, Jon Gambrell, and Jamey Keaten, Associated Press David Rising, Koral Saeed, Bassem Mroue, Aamer Madhani, and Josh Boak contributed.
