The week in 35 photos

Tensions between Ukraine and Russia are at their highest in years, with a Russian troop buildup near the border spurring fears Moscow could soon launch an invasion.

Russia has denied it is planning to attack, arguing that NATO support for Ukraine — including increased weapons supplies and military training — constitutes a growing threat on its western flank.

Negotiators from the two countries held hours-long talks in Paris on Wednesday and agreed that a permanent ceasefire in eastern Ukraine must be observed "unconditionally."

On the front lines, Ukrainian soldiers are still bracing for a possible attack. Some say it is inevitable.

"They've resigned themselves," photographer Timothy Fadek said. "But they're extremely relaxed. There is not a hint of nervousness in their faces. They're ready to fight. They've been ready for many years now."

Here are some of the stories that made headlines over the past week, as well as some photos that caught our eye.
