Fighters from Yemen’s Popular Committees launched the domestically-produced missile at the positions of the mercenaries in the Nihm district of the country's western Sana'a province on Monday afternoon, killing and injuring a large group of them, Yemen’s Arabic-language al-Masirah television network reported.
Following the missile launch, Yemeni ground troops scored gains against the militants in the district.
Separately, scores of Saudi-sponsored Hadi loyalists lost their lives and sustained injuries when Yemeni forces carried out two separate attacks against their outposts in the southwestern province of Ta'izz.
The attacks were carried out in retaliation for Riyadh’s relentless airstrikes on Yemeni civilians.
Yemen’s defenseless people have been under massive attacks by the coalition for more than two and half years but Riyadh has reached none of its objectives in Yemen so far.
Since March 2015, Saudi Arabia and some of its Arab allies have been carrying out deadly airstrikes against the Houthi Ansarullah movement in an attempt to restore power to fugitive former president Abdrabbuh Mansour Hadi, an ally of Riyadh.
Over 14,000 Yemenis, including thousands of women and children, have lost their lives in the deadly military campaign.
