They were found after a man had informed the authorities.
The Ministry of Oil said in a statement that the return of equipment and materials of the Beji refinery was based on the assistance of a loyal citizen and through several official and unofficial contacts, despite the efforts of the relevant parties.
The ministry added that the equipment and materials that were taken to several warehouses in the Kurdistan region and several places were distributed and identifying them was a difficult process.
The process of returning the equipment was after the citizen contacted the Oil and Energy Committee of the House of Representatives and the chairman of the committee who expressed his willingness to return them, some of which are not used, the statement noted.
The oil ministry said the equipment was returned in cooperation with the Kurdistan Regional Government (KRG) without any charges.
