Hear more context on the U.S. intelligence leaks and about previous ones from NPR national security correspondent Greg Myre.

Washington and Moscow have worked out prisoner swaps for decades, though they used to involve spies. Today, an increasing number of private American citizens are being jailed by Russia.

Many questions still remain about a data leak of classified documents related to the war in Ukraine and intelligence from other nations.

Dozens of classified U.S. documents detailing the war in Ukraine have appeared on multiple social media sites. There's no word on who might be responsible for leaking or stealing the material.

Maps and charts providing details on Ukraine's military and the state of the war have been published on Twitter and Telegram. The Pentagon says it is investigating how they were leaked or stolen.

There's lots of talk about China supplying weapons to Russia for its war in Ukraine. But one Chinese product already plays a key battlefield role - a cheap, popular, off-the-shelf, commercial drone.

The top U.S. and Russian defense officials spoke by phone, a rare occurrence during the past year of war in Ukraine. The aim was to bring down tensions after a U.S. drone crashed in the Black Sea.

Defense Secretary Lloyd Austin says the U.S. will continue flying 'wherever international law allows.' This comes a day after Russia downed a U.S. drone in the Black Sea.

President Biden announces a submarine deal with Britain and Australia to bolster the Western naval presence in the Pacific. The agreement is seen as part of a larger effort to counter a rising China.

The U.S. Department of Energy says with "low confidence" that COVID-19 might have originated in a lab leak. But the scientific evidence overwhelmingly points to a natural origin for the virus.

Russia's military has performed poorly, and Ukraine has defied expectations. But will these trends hold? Experts look at how the war could take a different path in its second year.

They used to be called Kremlinologists — American experts on the Soviet Union. Now there's a new generation of Putinologists who seek to interpret Russia by analyzing its authoritarian leader.

There's a lot of confusion about how U.S. fighter jets have come to be shooting so many objects out of the sky the past few days. The White House is under pressure to explain.

Over the weekend, the U.S. military shot down a trio of flying objects. One was in Alaska, another in Canada and a third over Michigan.

Given the hullabaloo over the Chinese surveillance balloon, you'd think something like this never happened before. But it has. At least four times in recent years.
