Republican Lt. Gov. Karyn Polito of Massachusetts signed a bill Friday, approved one day earlier by the state's Democrat-led Legislature, outlawing so-called bump stocks, accessories that allow semi-automatic firearms to mimic the rapid firing action of machine guns.

Massachusetts is the first state to enact a ban on bump stocks in the wake of last month's shooting in Las Vegas, the deadliest in modern American history.

Lebanese prime minister Saad Hariri announced his resignation Saturday, accusing his adversaries of political interference and citing a fear that he, like his father before him, would become the target of an assassination plot.

Hariri disclosed his surprise decision during a televised speech from Riyadh, the capital of Saudi Arabia, as NPR's Peter Kenyon reported to our newscast unit.

The drama. The loyalty. The speculation about who stays and who goes. The Trump administration has it all. And so did Donald Trump's run on The Apprentice.

Officials continued to urge tens of thousands of people living downstream from a precarious, slowly failing dam in northwestern Puerto Rico to evacuate Saturday. But the U.S. territory's severely compromised communications infrastructure meant it was not immediately clear how successful the warnings would be.

Numerous scientific agencies on both sides of the Pacific detected an earthquake Saturday near the site where North Korea set off a hydrogen bomb earlier this month, at first prompting speculation of another weapons test, before a consensus appeared to emerge that the tremor was a natural occurrence.

As a rule of thumb, it is not big news when multiple political rallies overlap on the same weekend in the nation's capital, a prime setting for anyone trying to send a message to the people in power.

But there are exceptions to every rule — and certainly an exception can be found in a large gathering of Juggalos airing a grievance against the FBI. (More on this later.)

In a move apparently meant to counter the Trump administration's tough approach to immigration enforcement, the California legislature approved a so-called "sanctuary state" bill Saturday that would establish new protections for people living in the country illegally.

It was all, in effect, over before it even began.

In the face of overwhelming popular and political opposition, a far-right activist canceled a press conference hastily scheduled for Saturday afternoon that some feared would provoke violent confrontations in the heart of San Francisco. This came less than 18 hours after organizers also called off two highly publicized right-wing rallies planned for the Bay Area this weekend.

A service member remains missing after a U.S. Black Hawk helicopter crashed off the coast of Yemen during what officials described as a training exercise.

U.S. forces rescued five other troops who also went down in the crash and are still searching for the sixth service member, according to U.S. Central Command. The incident took place about 20 miles from the southeastern coast of Yemen around 7 p.m. local time Friday.

The U.S. Secret Service had a command post stationed within Trump Tower in New York City before July, but that is no longer the case.

Cathy Milhoan, director of communications for the agency, in a phone call with NPR Thursday, confirmed the relocation took place in July. While the command post — where supervisors and backup staff cluster — remains nearby, she said for security reasons she could not disclose its current location.

It is still a young tradition, but since 2015, Kraft Heinz Co. and the NHL have taken annual submissions from communities across the U.S. — written pleas arguing why their small town's ice rink deserves to be crowned Kraft Hockeyville USA.

The honor — which includes $150,000 in money for rink renovations and the opportunity to host an official NHL preseason game — is bestowed upon the community that best demonstrates its passion for hockey.

A U.S. passport will only get you into North Korea for the rest of August, the State Department announced Wednesday.

Calling members of the transnational street gang MS-13 "animals" who like to let their victims "die slowly because that way it's more painful," President Trump on Friday sought to highlight his administration's efforts to crack down on illegal immigration, reduce violent crime and secure additional congressional funding for immigration enforcement.

A German court sentenced a 29-year-old British hacker who confessed to committing a cyberattack last November that temporarily took down Internet access for nearly 1 million German consumers, according to news reports.

The court in the city of Cologne handed down a suspended sentence Friday of one year and eight months, Reuters reports. The news service adds that the maximum sentence was 10 years; prosecutors had sought a sentence of two years.

A police officer attempting to help at the scene of a car accident was fatally shot, apparently by an occupant of the vehicle, near Indianapolis on Thursday.
