An Israeli scuba diver has salvaged an ancient sword off the country's Mediterranean coast that experts say dates back to the Crusaders. Israel's Antiquities Authority said Monday the man was on a weekend dive in northern Israel when he spotted a trove of ancient artifacts that included anchors, pottery and a meter-long (yard-long) sword. Experts say the area provided shelter for ancient ships and is home to many archaeological treasures, some dating back 4,000 years.
