A large metal structure washed up on North Beach in Primorsko this morning. It is stuck in the sand and hard to pull out, mayor Ivan Gaykov told BNT.
Crews on the beach are trying to move it.
It is not known where the object came from or how it ended up in the sea. It has parts that look like weld seams. It may be ship equipment, a cargo platform or the door of a shipping container.
