Today’s top stories

The U.S. military says it has completed a second wave of strikes against Iranian military targets, aiming at air defense sites, radar systems and mine-laying capabilities. In a statement issued late last night, it said these strikes were a response to recent Iranian attempts to attack commercial shipping in the Strait of Hormuz. An Iranian Guard Corps spokesperson said today that the U.S. strikes caused civilian and military casualties. Iran has retaliated by targeting U.S. assets in Kuwait, Jordan, Bahrain and Iraq. Travel warnings have been heightened for Americans traveling in the Middle East.

• 🎧 Around 4 million barrels of crude oil passed through the Strait of Hormuz daily in August, going largely undetected by Iran, new data from maritime intelligence firm TankerTrackers reveals. While this remains only a third of pre-war levels, it’s significant, NPR’s Hadeel Al-Shalchi tells Up First. Iran says it is nearing an agreement with Oman to temporarily reopen the waterway, having developed maps for a maritime control and traffic division. But Al-Shalchi says Iran has been radio silent in the past few days on the status of those talks. President Trump has said he isn’t in a rush to resume negotiations with Iran, but Iranian officials have recently been calling for a return to diplomacy.

Immigration and Customs Enforcement has now acquired enough body cameras to equip all its officers and agents, the agency says. For years, immigration officials have told lawmakers and advocates that they didn’t have enough devices for an agency-wide body-worn camera program. Federal immigration officers have been involved in more than two dozen shootings during the Trump administration’s immigration crackdown. These cameras may help alleviate concerns about transparency and accountability. Homeland Security Secretary Markwayne Mullin expects every field officer to have a body-worn camera by the end of September.

Sen. Ed Markey has won the Democratic nomination for U.S. Senate in Massachusetts. The 80-year-old progressive fended off a challenge from the more moderate Rep. Seth Moulton, who had called for generational change and a new direction in party leadership.

• 🎧 The Democratic party has been reckoning with the age of its elected officials, NPR’s Saige Miller says, but Markey was likely bolstered by his incumbent status and progressive politics in the predictably blue state. He has the support of prominent progressives like Sen. Bernie Sanders and Congresswoman Alexandria Ocasio-Cortez, who typically back younger candidates. Voters in Colorado, Michigan and Minnesota have chosen younger, more progressive candidates over longtime incumbents in several primaries, so Miller says Markey’s win is a reminder that every district is different and being seen as an effective lawmaker by the people you represent goes a long way.
