Officials in Nepal said today that at least 1,900 people are missing after an enormous flash flood tore through a Himalayan valley along the border with China, killing at least 580 people, but perhaps many more. The estimate of those missing is about double the previous tally, as Nepali forces continue to search the region. Officials said more than 3,700 people had been rescued so far, including some who were dragged out of the mud. The country’s disaster relief agency said the big jump in the number of missing came after hydropower producers in the flooded river valley reported that about 900 people connected with the projects were unaccounted for.

The Times has verified footage showing the moments after a giant glacier broke away from the top of a ridge in the Himalayas, setting off the deadly flood.

Oil stockpiles drop after six months of war. Exactly six months ago today, American and Israeli forces launched a massive attack on Iran, setting off a war. President Trump said the conflict would be quick and decisive, but the conflict is dragging on. In the U.S., the war has become very unpopular, in part because it has led to higher fuel costs. The federal government has been steadily depleting its Strategic Petroleum Reserve, which recently fell to its lowest levels since 1982. And private oil storage sites are holding a small fraction of their capacity.

In Iran, many people are losing hope. Six months ago, some Iranians believed that the U.S. intervention would help force the country toward a better future. Now, with many expecting the Islamic government to remain in power, the focus has shifted to surviving an economic crisis that the war has worsened. “People are hungry, confused and unable to find a way out,” an artist in Tehran said.

Fed chair seeks to calm inflation concerns. Kevin Warsh, the chairman of the Federal Reserve, said today that the central bank was chiefly focusing on getting inflation down after half a decade of it overshooting the Fed’s 2 percent target. The Fed, he said, had “work to do” if prices do not cool down. In his first speech as the main attraction at the Fed’s annual conference in Jackson, Wyo., Warsh stopped short of saying whether higher borrowing costs were on the horizon. But investors nevertheless raised their expectations for higher rates.

Trump orders the creation of a space academy. Declaring today that “space is the hot thing,” the president signed an executive order to establish a space academy, similar to the Naval Academy in Maryland or the Coast Guard Academy in Connecticut. Plans are still preliminary, but the order said that the academy would feed its graduates into the U.S. Space Force and NASA.
