Tehran, Sep 16 (TIWN) Iran on Sunday rejected US allegations that Tehran had carried out the drone attack at an oil field in Saudi Arabia, saying that Washington's maximum pressure strategy has turned into a strategy of "maximum lie" against the Islamic Republic.

Mousavi said that it was about five years that the Saudi-led coalition has waged a full-scale war on Yemen by repeated aggression and committing atrocity crimes against the civilians.

"Such accusations and blind statements are meaningless and incomprehensible in diplomatic standards," he noted.

The spokesman added that such allegations would "tarnish the image of a country aiming preparatory works for future actions".

The attack on Saturday, which was carried out by 10 unmanned aircraft, hit Hijra Khurais - one of Saudi Arabia's largest oil fields, producing about 1.5 million barrels a day - and Abqaiq, the world's biggest crude stabilization facility, which processes seven million barrels of Saudi oil a day, or about 8 per cent of the world's total output, Efe news reported.

It has disrupted about half of the Kingdom's oil capacity, or 5 per cent of the daily global oil supply.

Although the Yemeni Houthi rebels have claimed responsibility for the attack, Pompeo has denied, saying: "There is no evidence the attacks came from Yemen."
