Israel closed all its Mediterranean beaches until further notice on Sunday, days after an offshore oil spill deposited an estimated dozens of tons of tar across more than 100 miles of coastline in what officials are calling one of the country’s worst ecological disasters.
Activists began reporting globs of black tar on Israel’s coast last week after a heavy storm washed the petroleum byproducts ashore, wreaking havoc on wildlife. Researchers with the country’s Agriculture Ministry determined Sunday that a dead young fin whale that washed up on a beach in southern Israel died from ingesting the viscous black liquid, according to Kan, Israel’s public broadcaster.
Israel’s Nature and Parks Authority has called the spill “one of the most serious ecological disasters” in the country’s history.
In 2014, a crude oil spill in the Arava Desert caused extensive damage to one of the country’s delicate ecosystems.
The exact cause of the spill has yet to be determined and is currently under investigation by Israeli environmental officials.
Volunteers took to the beaches on Saturday to help clean up the tar, and several were hospitalized after they inhaled toxic fumes.
The Environmental Protection, Health and Interior Ministries issued a joint statement Sunday warning the public not to visit the entire length of the country’s 195 km (120 mile) Mediterranean coastline, cautioning that “exposure to tar can be harmful to public health.”
Environmental Protection Minister Gila Gamliel told Hebrew media that her department estimates the clean-up project will cost tens of millions of shekels.
Israeli Prime Minister Benjamin Netanyahu toured one of the country’s tar-pocked beaches on Sunday and praised the ministry’s work.
The ministry did not immediately respond to requests for an interview.
