SANAA, May 10 (Xinhua) -- Yemen's Houthi militia said they hit a "military target" inside Abha International Airport in southwestern Saudi Arabia with a bomb-laden drone on Monday evening.
"The hit was accurate," Houthi military spokesman Yehya Sarea was quoted by Houthi-run al-Masirah TV as saying, without providing further details.
Meanwhile, Saudi-owned Al-Arabiya TV reported that the Saudi air defenses intercepted and destroyed an armed drone the Houthi militia launched from Yemen at the Saudi airport.
Cross-border missile and drone attacks by the Iran-backed Houthis have escalated since February when the group began a major offensive against the Saudi-backed Yemeni government army to capture the oil-rich province of Marib in central Yemen.
On Wednesday, UN Special Envoy for Yemen Martin Griffiths said a recent UN-brokered negotiation between Yemen's warring sides and other relevant parties has failed to produce any agreement of cease-fire.
Yemen has been mired in a civil war since late 2014 when the Houthi militia seized control of several northern provinces and forced the internationally-recognized government of President Abd-Rabbu Mansour Hadi out of the capital Sanaa.
A Saudi-led Arab coalition intervened in the Yemeni conflict in March 2015 to support Hadi's government.
