A Yemeni Houthi (Ansarallah) strike targeted a desalination plant in the south-western Saudi province of Jizan, the Arab coalition said Thursday (June 20th).
The projectile struck near the plant in the al-Shuqaiq area of Jizan late Wednesday, coalition spokesman Turki al-Maliki was quoted as saying by the official Saudi Press Agency.
It reported no casualties or damage, adding that they were investigating the nature of the projectile.
The coalition will take "firm measures, urgent and timely, to deter this terrorist militia", al-Maliki said.
"The terrorist elements responsible for planning and executing these acts... will be held responsible," he said.
Late Wednesday, Yemen's Iran-backed Houthis said they fired a missile at a power station in Jizan province.
The White House said on Thursday that President Donald Trump had been briefed about reports of a missile strike on Saudi Arabia, without offering details.
Meanwhile, Arab parliamentarians gathered in Cairo on Wednesday urged the UN to list the Houthi militia as a "terrorist organisation".
The parliament of the Arab League decided Wednesday to "ask the UN and the Security Council to take a firm and immediate position by classifying the putschist Houthi militia a terrorist organisation".
The body accused the Houthis of "regularly targeting civilian and vital infrastructure in Saudi Arabia with ballistic missiles or drones".
