As Vladimir Putin's forces keep up their bombardment of Ukraine - with a "massive" strike on Kyiv overnight - one Ukrainian athlete wanted to make a statement at the Winter Olympics, but has now been banned.

Another round of U.S.-brokered talks between envoys from Russia and Ukraine will take place next week in Geneva, days ahead of the fourth anniversary of the all-out Russian invasion of its neighbor, officials in Moscow and Kyiv said on Friday.

Ukraine is deploying drone-delivered, anti-vehicle landmines to counter Russian assault tactics that are increasingly reliant on motorcycles, ATVs, and light vehicles.

The drone hangs motionless in a pale winter sky, then suddenly erupts into flame and tumbles earthward. There is no crack of gunfire, no roar of missiles and no visible beam, only the quiet whir of a camera tracking its target from what looks like a telescope bolted to the bed of a pickup truck.

The mother, who is 35 weeks pregnant, sustained blast injuries, a traumatic brain injury, burns and hearing loss, officials in Kharkiv said.

A security source told Business Insider that the drones struck a refinery in Russia's Komi Republic on Thursday.
