Cairo: An Arab Saudi-led alliance, fighting Al Houthis in Yemen, said its forces Friday intercepted and destroyed four explosive drones fired by the Iran-allied militia in the direction of the kingdom.

Three of the four were destroyed in the Yemeni airspace, spokesman for the coalition Col. Turki Al Maliki said.

"The Joint Forces have high efficiency in confronting these threats and aborting them by monitoring and destroying them directly after their firing from inside the militia-controlled areas [in Yemen]," he added, according to the Saudi news agency SPA.

The destroyed drones were the latest in a series of attacks by Al Houthis targeting Saudi Arabia.

The rebels plunged Yemen into a devastating conflict in late 2014 when they toppled the internationally recognised government and overran the capital Sana'a and other parts of the impoverished country.
