The latest news on Russia and Ukraine. On Wednesday, US special envoy Keith Kellogg has voiced alarm over a sharp rise in geopolitical risk following Ukrainian drone strikes on Russian airbases housing strategic bombers (Ukraine's Operation Spider's Web).
The unprecedented reach of the attacks has sparked fears about provoking a nuclear power's defence apparatus. Kellogg stressed the psychological weight of these hits, especially as peace talks in Istanbul stalled with opposing demands on both sides.
