Yep, pretty strict laws in Israel. Here's an excerpt from Wikipedia outlining the law on antiquities.
"When an antiquity is discovered or found in Israel, it becomes the property of the State. The person who discovers or finds an antiquity is required to notify the Director of the Israel Antiquities Authority within fifteen days of the discovery or find. A person claiming to have discovered or found the antiquity before the development of this law is required to provide proof. The Director may waive State ownership of an antiquity in writing.
No person is allowed to dig or search for antiquities, including the use of a metal detector. No person is allowed to gather antiquities unless the person has obtained a license to do so from the Director. If a person is found on an antiquity site with digging tools in his/her possession or nearby then the person is presumed to have intended to discover antiquities."
