A polluted area caused by an oil spill is seen at the Evrona desert reserve, near the Red Sea resort city of Eilat December 10, 2014. Ecologists said on Wednesday it could take years to clean up the massive oil spill that flooded an Israeli nature reserve with up to five million litres of crude and threatened to spread to the Red Sea shore and neighbouring Jordan.
