Tehran, November 18 (KCNA) -- Iran's President Mahmoud Ahmadinejad in an address to the staff of an oil refinery on Wednesday called for shattering the moves of the enemies.

He said that disappointed enemies who cannot tolerate to see Iran's great success and development try to level various accusations against the country.

Preparing various scenarios and leveling accusations are parts of their plot in reaction to Iran's scientific breakthrough, he said.

He also called for improvement of the refinery's products both qualitatively and quantitatively.

Engineers and contractors involved in the oil industry should play more active role in global oil markets, he said.
