Iran has vehemently denied allegations by US Secretary of State Mike Pompeo that the country has been involved in drone strikes on the largest oil refinery in Saudi Arabia. Pompeo's insinuations are absurd, inexplicable and therefore also halted and ineffective, according to Foreign Ministry spokesman Abbas Mousavi. What happens in Yemen is Yemeni resistance to the war crimes of the military coalition led by Saudis, the spokesman said, according to news agency Isna.

Mousavi continued, "Because the US policy of maximum pressure on Iran failed, the Americans have now switched to maximum lies." Despite extreme hostility, the statements of politicians should have "a minimum of credibility", which is not the case for the Americans at present.

Pompeo blamed Iran for a drone attack on an oil refinery in Saudi Arabia. "In the midst of calls for de-escalation, Iran has now committed an unprecedented attack on world energy supply, and there is no evidence that the attacks came from Yemen," wrote Pompeo on Twitter.

Tehran is behind nearly 100 attacks on Saudi Arabia while Rouhani and Zarif pretend to engage in diplomacy. Amid all the calls for de-escalation, Iran has now launched an unprecedented attack on the world's energy supply. There is no evidence the attacks came from Yemen.

Huthi rebels claimed responsibility for the attack

In fact, the Shiite Houthi rebels were known in Yemen for the attacks. The ten-drone attack provided a legitimate response to Saudi Arabia's ongoing military campaign in Yemen, said Huthis military spokesman Jahia Saria. "We promise the Saudi regime that our next operation will be bigger and more painful," said Saria.

During the attack on an oil field and a large oil processing plant, a fire broke out during the night of Saturday, which could now be brought under control. According to a spokesman for the Saudi Ministry of the Interior, the attacks took place at the two locations of Abkaik and Khurai in the east of the kingdom.

The Iranian and Saudi governments have been delivering a proxy war in Yemen for several years, with Iran supporting the Houthi rebels. In recent months, the rebel group has already claimed similar attacks in Saudi Arabia.
