Four oil tankers, including vessels managed by Greek companies, were reportedly hit by drones near Russia's Caspian Pipeline Consortium (CPC) terminal in the Black Sea. The attacks, which occurred on January 13, have raised concerns about potential increases in shipping and insurance costs. This incident follows a previous drone strike on a CPC mooring in November, which contributed to a significant drop in Kazakhstan's oil output due to export constraints. While Ukraine has targeted Russian energy infrastructure, responsibility for these latest attacks remains unconfirmed.
