Washington, April 4 -- Iran shot down a US fighter jet for the first time in the war and targeted more sites, including energy facilities, in Arab Gulf states even as a handful of ships transited the Strait of Hormuz by using a new route hugging the Omani coastline. The developments came amid reports that said attempts to broker a ceasefire had stalled. One of the crew members of the F-15E fighter jet was rescued, according to a US official, who asked not to be identified discussing sensitive information. A search-and-rescue operation is underway for the second crew member, the official said. President Donald Trump was briefed on the incident, the White House said. US Central Command didn't respond to an earlier request for comment on the downed jet. The first known combat loss of a US or Israeli fighter jet would mark a significant blow to the alliance after a war of almost five weeks that has triggered a global energy crisis. Iran's semi-official Tasnim news agency reported Friday that the country had shot down a "highly advanced American fighter jet." Other Iranian media published photos showing what they said was wreckage of a downed jet. Prior to word of the rescue, social media footage showed American drones, aircraft and helicopters flying over the mountainous region in Kohgiluyeh and Boyer-Ahmad Province where a TV channel affiliated with Iranian state television said at least one pilot bailed out of the fighter jet. An anchor on the channel urged residents to hand over any "enemy pilot" to police and promised a reward. The Iranian government is yet to comment on the incident. The Wall Street Journal reported that current mediation efforts led by regional countries, including Pakistan, to broker a cease-fire between the United States and Iran have reached a dead end. Iran has officially told mediators that it is unwilling to meet US officials in Islamabad in the coming days and considers US demands unacceptable, the report said. Iran kept up attacks across the region after Trump renewed threats against Iranian infrastructure. The United Arab Emirates' largest natural gas processing facility, Habshan, suspended operations after debris from a projectile interception sparked a fire. Hours earlier, a drone attack set ablaze Kuwait's Mina Al Ahmadi oil refinery, with a capacity of 346,000 barrels a day. Kuwait also reported damage to a power and water desalination plant after an attack early on Friday, and Saudi Arabia said it intercepted several drones in the early morning. On Thursday, Trump posted a video of a destroyed bridge and said there would be "much more to follow" if Iran didn't agree to a deal to end the almost five-week old conflict, which has caused a global energy crisis. Iran remained defiant, with Foreign Minister Abbas Araghchi saying strikes on civilian structures "will not compel Iranians to surrender."...
