Roza Barakat's tormentors have been defeated, but the horrors she endured still hold her captive.

She was 11 years old when she was captured and enslaved by the Islamic State group, along with thousands of other Yazidi women and girls taken when the militants overran northern Iraq in their brutal 2014 campaign.

When the U.S. and NATO rejected the Kremlin's security demands over Ukraine last week, fears of an imminent Russian attack against its neighbor soared.

But instead of sending armored armadas across the Ukrainian border as the U.S. and its allies worried, Moscow bombarded Western capitals with diplomatic letters about an international agreement that the Kremlin sees as a strong argument for its position in the standoff.

A day after the death of Islamic State leader Abu Ibrahim al-Qurashi during a U.S. raid in Syria, many questions remain on the operation and the jihadist group's future.

A series of high level talks are in the works on Tuesday to avert the threat of war as Russian troops mass by the tens of thousands on the borders of Ukraine.

Russian President Vladimir Putin is expected to make an appearance with the Hungarian prime minister, while British Prime Minister Boris Johnson is taking a break from his troubles at home for a meeting in Kyiv with Ukrainian President Volodymyr Zelenskyy. The Kremlin also announced Putin's in-person meeting with French President Emmanuel Macron "in the foreseeable future."

High-stakes diplomacy continued on Friday in a bid to avert a war in Eastern Europe. The urgent efforts come as 100,000 Russian troops are massed near Ukraine's border and the Biden administration worries that Russian President Vladimir Putin will mount some sort of invasion within weeks.

Here are things to know about the international tensions surrounding Ukraine.

France's Macron takes own path, seeks dialogue with Russia

There's still room for diplomacy in the Ukrainian crisis. At least that's the conviction of French President Emmanuel Macron, who continues to push for dialogue with Russia despite signs pointing to a potential war.

Twice in the past week, Yemen's rebels have launched attacks with missiles and drones on the United Arab Emirates, a major escalation for one of the world's most protracted conflicts.

The attacks underscore how the war that has ground on for over seven years in the corner of the Arabian Peninsula can flare into a regional danger. One of this week's attacks targeted an Emirati military base hosting U.S. and British forces.

Lebanon's Saad Hariri, who announced on Monday that he was withdrawing from political life, was thrust into the limelight by his father's assassination but always struggled to fill his shoes.

As winter deepens, a grim situation in Afghanistan is getting worse. Freezing temperatures are compounding misery from the downward spiral that has come with the fall of the U.S.-backed government and the Taliban takeover.

Aid groups and international agencies estimate about 23 million people, more than half the country, face severe hunger and nearly 9 million are on the brink of starvation. People have resorted to selling possessions to buy food, burning furniture for warmth and even selling their children.

On a warm spring day in Ukraine 26 years ago, three men smiled for cameras as they planted symbolic sunflower seedlings in freshly tilled earth where Soviet nuclear missiles had once stood ready.

That placid scene was, briefly, a launchpad for hope that the demise of the Soviet Union would bury the threat of great power war and mark the start of lasting peace in an undivided Europe. Today Ukraine is ground zero for worry that Russia will ignite a conflict that could engulf the region.
