Lebanese officials say an oil spill from a power plant hit by Israeli war planes threatens to become one of the Mediterranean Sea's worst environmental disasters.

They say some 15,000 tons of oil from the Jiyeh plant is fouling more than 70 kilometers of Lebanon's shore. Israeli planes bombed the plant two weeks ago. Authorities say four of the plant's tanks have burned completely, a fifth is still on fire and they fear a sixth tank could explode.

The officials say the oil slick is moving up the Lebanese coast toward Syria and could eventually affect other countries' shorelines. Fishermen along the coast say the spill is already affecting marine life.

Kuwait has sent equipment to help clean up the oil.
