The Yemeni defense forces fired as many as three ballistic missiles during the Wednesday operation against the Dhahran al-Jonoub Province in Asir, the Yemeni Armed Force's Spokesman Brigadier General Yahya Saree announced on his Twitter account.
He specified the exact target of the operation as a camp belonging to the Saudi army's First Regiment.
The Yemeni forces also fired two ballistic missiles against the training camp belonging to the Saudi-led mercenaries in the western part of the southwestern Yemeni province of Ta'iz.
Two more such projectiles were, meanwhile, used in another counterstrike targeting the militants in the west-central province of Ma'rib.
Saudi Arabia and its allies launched a war against the Arab world's most impoverished nation in March 2015. The war has been seeking to restore power in Yemen to Riyadh's favorite officials.
The military campaign has stopped short of the goal, while killing tens of thousands of Yemenis and turning the entire country into the scene of the world's worst humanitarian crisis.
The Yemeni defense forces have, however, vowed not to lay down their arms until liberation of the entire country.
They have made significant advances towards ridding Ma'rib of the foreign military presence.
Given Ma'rib's strategic location, the province’s recapture is expected to pave the way for further military victories for Yemen’s defenders.
