The U.S. military says three Navy ships came under attack yesterday while navigating through waters near Iran. U.S. Central Command says it responded by launching strikes on Iranian missile and drone sites. Iran says that the U.S. started Thursday's violence by attacking one of its oil tankers in the Strait of Hormuz. This incident marks the first report of U.S. airstrikes on Iranian soil since the ceasefire began a month ago.

Republicans in Tennessee passed a new congressional map yesterday that would divide Shelby County — home to the majority-Black Memphis — into three districts. The action aims to eliminate the state's only remaining Democratic-held seat. Currently, Tennessee is represented by eight Republicans and one Democrat. The state is the first to redraw its congressional map after the U.S. Supreme Court last week weakened the Voting Rights Act's protections against racial discrimination in redistricting.

Global public health authorities are working to contain a hantavirus outbreak that began on a cruise ship early last month. There have been eight cases reported, including three fatalities. The ship is currently off the coast of Africa, but dozens of passengers have already disembarked and flown to destinations in Turkey, New Zealand and the United States. Despite a series of alarmist headlines, the World Health Organization emphasizes that the risk to the general public remains very low. Here's what else you should know about the hantavirus outbreak, including what the symptoms are, how it spreads, how the U.S. has responded and more.

The Court of International Trade struck down a second round of worldwide tariffs that Trump ordered to replace the import levies that the U.S. Supreme Court ruled were unlawful. The international court's decision was limited to two importers who contested the tariffs, as well as the state of Washington. It was not immediately clear whether other importers will still be required to pay these levies. When the Supreme Court ruled in February that the president exceeded his authority with his tariffs on almost everything the U.S. imports, the president sought to replace the import taxes using a different law. The trade court ruled that the law applies tariffs only to large and persistent balance-of-payments deficits, which do not currently exist. The international court found the replacement tariffs unwarranted.

This year's NPR College Podcast Challenge winner takes the form of a letter to a grandparent. In Dear Papa, contestant Colby McCaskill intertwines scenes from a past visit with his grandparents with interviews and personal reflections on their aging and declining health. McCaskill's grandmother has dementia, and he doesn't shy away from the reality of her condition. Like millions of Americans with the same disease, she is losing her memory. She struggles to remember names, her age and how to perform basic tasks. "Being with my grandparents is like a warm hug," McCaskill said after winning. "[The podcast] was an opportunity to get my thoughts down and to make it clear: This is what I'm thinking and this is how I'm feeling and I want you to know this." NPR judges say the episode stood out among the many entries for its intimacy and vulnerability. Listen to the podcast or read more about its development.
