Yemen’s Arabic-language al-Masirah television network said the attack targeted “the leadership of the invaders” on Thursday. It said several army personnel were killed in the raid, without specifying the number.
Saudi-owned broadcaster Al-Arabiya said five were killed and several others injured when the combat drone struck a military base in al-Anad district, where a military parade was taking place.
Some 12 more coalition forces were also wounded in the retaliatory attack, according to the report.
Saudi Arabia and a number of its regional allies launched a devastating military campaign against Yemen in March 2015, with the aim of bringing the former Riyadh-backed government back to power.
The invaders have, however, failed to achieve their objective in the face of strong resistance by Yemeni Houthi fighters and allied armed forces.
