CIA Director Bill Burns made a rare public speech Thursday and talked about the agency's role in Ukraine. Also, hundreds of suspected Russian spies have been kicked out of embassies in Europe.

Russia is now concentrating its forces in eastern Ukraine and a major offensive is widely anticipated. But this new stage of the war could differ in many ways from the past seven weeks of fighting.

Ukraine's military has fought so effectively that Russia abandoned its initial plan, which envisioned a quick takeover of Kyiv. Now Russia has a new approach, which focuses on eastern Ukraine.

The Russians are pulling some troops away from Ukraine's capital Kyiv. But what exactly does this mean? U.S. and Ukrainian officials suspect Moscow may just be pausing before another big offensive.

Russia says it put its nuclear forces on a higher state of alert, and Western officials have raised the prospect of chemical weapons attacks. How serious are these threats?

Russia's war in Ukraine has prompted an exodus from Russia, including many Americans living there. Some had built a life stretching over decades. Now they don't know if they'll ever go back.

Ukraine may be outgunned, but to the surprise of many, it has punched back hard against Russia. The U.S. is supplying lots of Ukraine's most effective weapons, which are coming into the country daily.

Ukraine is outgunned by Russia but is making the most of its mobile weapons that allow Ukrainian troops to be more nimble. Some of the most important weapons are from the United States.

The package by the White House includes missiles to take out tanks and bring down Russian aircraft — as well as drones that the U.S. hasn't provided previously.

The U.S. and Russia have talked for years about "hybrid war" — waging a conflict on multiple fronts beyond the battlefield. In unprecedented ways, the U.S. is now employing this against Russia.

Russia unleashes a heavy bombing campaign. Cities are reduced to rubble. Thousands of civilians are killed. Russia did that twice in Chechnya in the 1990s. Is a repeat likely in Ukraine today?

CIA Director William Burns says Russia's invasion of Ukraine has fallen far short of Vladimir Putin's expectations. Burns now predicts weeks of "ugly" fighting for control of Ukraine's cities.

The reported Russian effort to find Syrians with urban combat experience is the latest indication that Russia's invasion of Ukraine is not going as planned.

Before the war, Ukrainian Rehina Solodovnik tutored Russian students online. The teaching has stopped, but she's still getting text messages. "I am so sorry for our government," one student said.

The Pentagon says it has no reason to doubt Russia's claim that it's in control of the Zaporizhzhia nuclear power plant as the invasion of Ukraine continues. There is no sign of radioactive leakage.

The early days of Russia's war with Ukraine haven't gone well on the battlefield, in the global information war, or on the economic front. But Russia still has weapons it can unleash.

Ahead of President Biden's State of the Union address, NPR's Ari Shapiro previews the State of the Union address with NPR reporters and correspondents.

President Biden says the Russian invasion of Ukraine is unfolding largely as predicted. Accurate U.S. intelligence didn't prevent the attack, but it did counter Russian disinformation.

The Russian incursion in Ukraine has sparked fears of an invasion, but the information war is already in full swing.

A Russian invasion and occupation of Ukraine would cost billions. Russia's weak economy would face tough sanctions. And there are the political costs of alienating Europe and revitalizing NATO.
