The Saudi-led Arab coalition said on Monday it had detected hostile escalation by the Iran-backed Houthi militias in Yemen.
It revealed that the Houthis had launched "a number of armed drones from Sanaa international airport."
"We have detected and continue to monitor the hostile escalation," it stressed.
The coalition later said it destroyed three drones launched in the direction of southern Saudi Arabia.
Earlier, the terrorist Houthis said they carried out an attack on the United Arab Emirates after authorities in the Gulf state reported two fires in the capital Abu Dhabi that were possibly caused by drones.
Abu Dhabi police said three fuel tanker trucks had exploded in the industrial Musaffah area near storage facilities of oil firm ADNOC and that a fire broke out at a construction site at Abu Dhabi International Airport.
"Initial investigations found parts of a small plane that could possibly be a drone at both sites that could have caused the explosion and the fire," the police said in a statement on state news agency WAM.
