Saudi citizens have complained after finding Israeli scout uniforms, with Israeli flag tags, being sold in shops in the kingdom.
Pictures of the uniforms, taken in the southern province of Jizan, were shared on social media.
Saudis criticised what they said was a "Zionist invasion" of Saudi Arabia, while others said it was a result of a push by the Saudi crown prince, Mohammed bin Salman, to normalise relations with Israel.
Many claimed they were "military uniforms".
The uniforms were reported to the Saudi commerce and investment ministry by a Saudi citizen.
According to Saudi Arabia's Akhbar 24 website, the official representative of the ministry, Abdulrahman al-Hussein, said that the regulatory authorities "are called to complete the procedures and the imposition of systematic penalties".
In June 2017 King Salman of Saudi Arabia issued a royal order which exempted Mohammed bin Nayaf of his post and appointed his son Mohammed bin Salman as the crown prince of the kingdom.
Bin Salman has launched a crackdown on alleged corruption in the kingdom and has orchestrated a sweeping purge targeting writers, scholars and popular figures on social media.
