A fishing boat full of drunken sailors accidentally rammed a nuclear submarine off the coast of Kamchatka early Thursday, Interfax reported, citing Navy sources.

The crew of the Svyatoi Georgy, or St. George, which had surfaced and had its navigation lights turned on, saw the fishing boat coming, but attempts to contact its crew via radio or get their attention with flares proved unsuccessful, likely because the captain was not at the bridge, and the entire crew was drunk, the report said.

Both ships suffered minor damage as a result of the collision, which caused no injuries. There was no radiation leak, but the submarine is undergoing repairs.

The collision is the latest in a summer of maritime debacles in Russia. In late July, an overloaded party boat rammed into a moored barge on the Moscow River, sinking on the spot and killing nine people. Earlier that month, the Bulgaria riverboat capsized and sank, claiming the lives of 122.
