Houthi spokesman Yahya Sarea said Thursday’s drone strike on a military base in Lahaj province, which killed several high-ranking officials, was a “legitimate operation against aggression”.
He said the movement was building a stockpile of locally manufactured drones.
“Soon there will be enough in the strategic stockpile to launch more than one drone operation in multiple battlefronts at the same time,” Sarea told reporters in Sana’a, according to Reuters.
Dozens of forces loyal to fugitive former president Abd Rabbuh Mansur Hadi were killed and 11 injured in Thursday's incident.
Among those injured were ex-Yemeni deputy chief of staff Saleh al-Zandani, senior army commander Fadel Hasan and Lahij governor Ahmad Abdullah al-Turki.
Turki and Zandani were transported to Saudi Arabia for treatment, a source said.
Following a truce agreed in Sweden in December, the UN is working to schedule a new round of consultations, possibly in Kuwait, aimed at drafting a political framework for resolution of the conflicts in Yemen.
