The Dutch navy says it has discovered the sunken wreck of a German World War I submarine off the island of Terschelling and will designate it a war grave.

The Defense Ministry says the wreck of the U-106 is lying on the seabed 40 meters (130 feet) underwater and 65 kilometers (40 miles) north of Terschelling, an island in the Wadden Sea off the northern Netherlands.

The submarine was first discovered in October 2009, but the find was only announced Wednesday after the Dutch Defense Ministry authorities confirmed its identity with German authorities.

The Dutch navy initially believed the wreck was a Dutch submarine, 0-13, that went missing during World War II, but divers and remote cameras later confirmed it was the U-106.
