Yemen’s Houthi rebels said they launched a bomb-laden drone into Saudi Arabia, targeting an airport with a military base – an attack acknowledged by the kingdom.
It was not clear if there were any injuries or what the extent of damage was.
The Houthis’ Al-Masirah satellite news channel said early on Tuesday the attack targeted the airport in Najran with a Qasef-2K drone, striking an “arms depot”.
Najran, 840km southwest of Riyadh, lies on the Saudi-Yemen border and has repeatedly been targeted by the Houthis.
A statement earlier on the state-run Saudi Press Agency quoted Saudi-led coalition spokesman Col. Turki al-Maliki as saying the Houthis “had tried to target” a civilian site in Najran, without elaborating.
Al-Maliki warned there would be a “strong deterrent” to such attacks and described the Houthis as the “terrorist militias of Iran”.
Similar Houthi attacks in the past have prompted rounds of Saudi-led air raids on Yemen, which have been widely criticised internationally for killing civilians.
Civilian airports throughout the Middle East often host military bases.
The New York Times last year reported that US intelligence analysts were based in Najran, assisting the Saudis and a US Army Green Berets deployment on the border.
The Pentagon and the US military’s Central Command did not immediately respond to requests for comment.
The Yemen conflict has killed tens of thousands of people since a Saudi-led military coalition intervened with a devastating aerial bombardment campaign in support of the beleaguered government in March 2015, after the Houthis removed President Abd-Rabbu Mansour Hadi and forced him out of Sanaa, the capital.
The fighting has triggered what the UN describes as the world’s worst humanitarian crisis, with 3.3 million people still displaced and 24.1 million – more than two-thirds of the population – in need of aid.
