Israeli authorities said Wednesday that a Libyan-owned tanker suspected of smuggling oil from Iran to Syria was responsible for spilling tons of crude into the eastern Mediterranean last month, causing one of Israel’s worst environmental disasters. Over 90% of Israel’s 195 kilometer (120-mile) Mediterranean coastline was covered in more than 1,000 tons of black tar, the result of the mysterious oil spill in international waters. Environmental Protection Minister Gila Gamliel said the Panamanian-flagged “pirate ship owned by a Libyan company” — identified as the “Emerald” — filled its stores with oil in the Persian Gulf, then sailed with its transmitters off toward the coast of Syria.
