Houthi spokesman Mohammed Abdulsalam on Tuesday said on Twitter that the attack on Saudi oil facilities was a response to the Saudi attacks on his group, vowing Houthis' readiness to launch more such attacks.
Its close ally, the UAE, said it was "committed to de-escalation" after the spike in Gulf tensions, but warned it would retaliate hard against Yemen rebel attacks on civilian facilities in the region.
Saudi Energy Minister Khalid al-Falih, in comments run by state media, said the drone attack and Sunday's sabotage of four vessels, including two Saudi tankers, off Fujairah emirate, a major bunkering hub, threatened global oil supplies.
Saudi Aramco, the government-controlled oil company, said that as a precaution, it temporarily shut down the East-West Pipeline and contained a fire, which caused minor damage to one pumping station.
Saudi Arabia, the world's biggest oil exporter, is likely to raise its production much more cautiously than previous year when production from the Kingdom rose to record highs above 11 million bpd in November after calls from Trump to replace Iranian barrels.
Saudi Arabia said the two petroleum pumping stations that were struck by drones are located in the greater region of Riyadh, home to the landlocked capital.
Fighter jets of the Arab coalition to restore legitimacy in Yemen carried out airstrikes on a Houthi camp, killing insurgents and destroying combat vehicles, the Saudi Press Agency reported on Wednesday.
Saudi Arabia and the UAE back the sanctions against Iran, a fellow OPEC producer but regional foe. In the same year, terrorists from the same group attacked property at the SADAF Petrochemical Complex in the eastern Saudi city of Jubail. United States intelligence sources have alleged Iran is behind the unexplained attacks, but added Washington does not have enough proof to back that claim. The terror cell had received instructions from a Syria-based intermediary in Syria.More news: Comedian Tim Conway of ‘The Carol Burnett Show’ dies at 85

Gen. Chris Ghika, a senior officer in the USA -backed coalition fighting the Islamic State group, said Tuesday, insisting "there's been no increased threat from Iranian-backed forces in Iraq and Syria". The impact on global oil prices is normally not that substantial, as long as the supply continues. Trump says it's "fake news", but that he would "absolutely" be willing to send troops if necessary.
Notably, the recent attacks come amid mounting tension between Iran and the US after the Pentagon announced the deployment earlier this week of an aircraft carrier strike group to the Persian Gulf. "It is easy to throw accusations but it is a hard situation, there are serious issues and among them is Iranian behavior", he said, mentioning concern about Iran's missiles and regional policy.
A UAE government official said the Saudi oil tankers Al-Marzoqah and Amjad were attacked off the emirate of Fujairah along with the Norwegian tanker Andrea Victory and an Emirati ship, the A. Michel. The other three showed no visible damage from above.
USA national security agencies believe proxies sympathetic to or working for Iran may have been behind it, a US official has said.
Iran rejects the allegation of Iranian involvement and Iranian Foreign Minister Mohammad Javad Zarif said that "extremist individuals" in the US government were pursuing risky policies.
However, he blamed "Iranian behaviour" for Gulf tensions.
