A cargo ship owned by the Israeli shipping giant Zim sank in the Black Sea after being attacked by at least three naval drones. The attack occurred 17 nautical miles (31.5 kilometers) from Cape Kaliakra, within Bulgaria's exclusive economic zone. The ship left the port of Haifa and headed for the Romanian port of Constanta.
The ship carried lithium-ion batteries, corrosive liquids and acids, as well as a number of other defense-related materials. According to the Bulgarian government, initial tests showed no signs of contamination.
