Yemen's Houthi leader said on Friday the group would continue to develop its military capabilities as the Iran-aligned movement stepped up its attacks against Saudi Arabia in the Yemeni war.
Saudi air defence forces on Wednesday intercepted three missiles fired at Riyadh and other cities by the Houthis -- the fourth time in five months that missiles have flown over the Saudi capital. They also downed two Houthi drones in cities in the south of the kingdom, Saudi state media said.
"As long as the aggression continues, our military capabilities will grow and develop," Abdul Malik al-Houthi said in a speech aired by the Houthi-run Al Masirah TV, adding that the group had a right to build drone planes and use them.
A Saudi-led alliance intervened in Yemen's civil war in 2015 to try and push back the Houthis after they drove the internationally recognized government into exile in Riyadh.
The Houthis say their missile attacks on the kingdom are in retaliation for air raids on Yemen by the Western-backed coalition, which has launched thousands of air strikes in Yemen since 2015 that have killed hundreds of people.
The coalition accuses the Houthis of being armed and supported by regional foe Iran -- charges the group and Tehran deny.
Arms monitor Conflict Armament Research says it has evidence that the drones used on Wednesday and other Houthi equipment were made in Iran and was not of indigenous design and construction.
