A suspect in Friday's truck attack in Stockholm has been arrested, according to a Swedish prosecutor.

Police in Sweden say the man they have arrested is "likely" the driver of a truck which drove into pedestrians on a major shopping and tourist street in Stockholm, causing multiple injuries and fatalities.

Twitter is suing the Department of Homeland Security after the agency demanded to know the identity of the person behind the "@ALT_uscis" or "Alt Immigration" Twitter account, one of several "rogue" accounts ostensibly created by anonymous employees of the federal government.

A federal appeals court has rejected a lawsuit against Mississippi over the use of the Confederate battle flag in the state flag.

A black Mississippi resident said that the use of the Confederate symbol amounted to state-sanctioned racial discrimination. But the 5th Circuit Court of Appeals ruled that any emotional harm caused by the flag is irrelevant, legally speaking, and doesn't give him grounds to sue.

Authorities in New York have charged a white supremacist from Baltimore with terrorism over the murder of a black man last week.

Police say 28-year-old James Jackson of Baltimore traveled to New York City specifically to kill black men.

It was a plan he carried out on Monday, stabbing 66-year-old Timothy Caughman to death on a public street corner, police say.

The Associated Press reports that Caughman was remembered "as a gentleman and a good neighbor."

The Associated Press has tallied up business lost in North Carolina because of the controversial "bathroom bill," and estimates the total cost is at least $3.76 billion over 12 years.

That estimate is probably low, the wire service says.

Airlines have surprisingly strict dress codes for people traveling on "buddy passes," and astonishingly tone-deaf explanations.

Those are two takeaways from a story on Sunday that prompted shock and outrage on social media.

It's a love story for the ages: a boy, a girl and more than a million bugs.

Lois and Charlie O'Brien, two octogenarian entomologists, have spent their life together chasing insects around the world — some 60 years of romance and field work. Now the married scientists are donating their vast insect collection to Arizona State University.

At an hours-long public hearing on Monday, FBI Director James Comey confirmed that his agency is investigating possible coordination between the Trump campaign and Russia, and he pushed back against President Trump's allegations that he was wiretapped by former President Barack Obama.

The Trump administration is appealing a federal judge's decision to temporarily block the president's second travel ban from going into effect — setting up another legal showdown in an appeals court.

The first version of the ban, temporarily suspending the U.S. refugee program and barring entry into the U.S. from residents of seven majority-Muslim countries, was quickly blocked by a federal judge in Washington state. The Justice Department appealed that temporary restraining order, but a panel of judges from the 9th Circuit Court of Appeals upheld the suspension of the ban.

The U.S. Women's National Hockey Team — the reigning world champions — won't be defending their title this year. They announced Wednesday that they will be boycotting the championships later this month as a protest against USA Hockey, citing stalled negotiations for "fair wages and equitable support" from the organization.
