Limpet mine likely damaged Greek tanker near Libya in latest mystery attack, sources say

Three oil tankers were damaged by blasts in separate incidents around the Mediterranean in January and February, with the causes unknown.

The incidents are the first involving blast damage to non-military vessels to have taken place around the central Mediterranean for decades.

A fifth tanker suffered damage from explosions when it was anchored in Ust-Luga port in February, which prompted divers to search for mines around Russian ports.
