A leaking oil tanker split in two and sank Tuesday off Spain's northwestern coast, spewing thousands of tonnes of fuel oil into the sea and adding to a growing environmental disaster along one of Europe's most picturesque and wildlife-rich coasts. The two halves of the 26-year-old single-skinned vessel went down in deep
