Satellite images reveal a significant oil spill in the Kerch Strait, following the grounding and sinking of two oil tankers during a storm. The spill, estimated at up to 5,000 tonnes, is considered Russia's worst environmental disaster of the 21st century. The oil has spread across the Black Sea and Sea of Azov, impacting marine life and raising concerns about long-term ecological damage. Experts warn of severe consequences for wildlife, including thousands of affected birds and dolphins. Investigations into the seaworthiness of the vessels are ongoing.
