Iran's foreign ministry on Friday rejected accusations by Saudi Arabia that Tehran had ordered an attack on Saudi oil installations claimed by Yemen's Iran-aligned Houthi militia.
US-ally Riyadh made the accusation amid growing tension between Iran and its arch-foe the United States, which has built up its military presence in the region alleging threats from Iran to its troops and interests.
The Houthis, which have been battling a Saudi-led military coalition for four years, said they carried out Tuesday's drone strikes against the East-West pipeline, which caused a fire but Riyadh said did not disrupt output or exports.
"You're still deluded after 1,500 days, isn't that enough?," Iran’s foreign ministry spokesman, Abbas Mousavi, said on his Twitter account, referring to the length of the Yemen war.
