Lebanese and Switzerland have signed a protocol to clean oil slick from the Lebanese coasts caused by Israeli air strike during the 34-day Israel-Hezbollah conflict, local ANB TV station reported on Wednesday.

The protocol stipulated cleaning oil spills of the coasts stretching from Anafeh to Tripoli, the report quoted a statement released Tuesday by the Lebanese Ministry of Environment.

It said the protocol was part of Switzerland's aid program to Lebanon, which includes rebuilding schools and water projects.

The protocol will cost 400,000 dollars and will be spent within the Lebanese-Swiss cooperation framework, the report said.

Israeli warplanes bombed Jiyyeh, 25 kilometer south of Beirut, on July 14, spilling an estimated 30,000 tons of fuel oil into the Mediterranean sea.

The spill has moved at least 120 km to the north and reached the Syrian coast.

Environmental groups described the spill as the most serious environmental disaster in the country's history.
