In a unique operation launched on Friday by the Yemeni army troops near the port city of Mocha in Taiz, 40 mercenaries of the fugitive former President Abd Rabbuh Mansour Hadi, a close ally of Riyadh, were killed and dozens more were wounded, Lebanon’s Arabic-language Al Mayadeen TV quoted the sources as saying.

In another development, heavy clashes erupted between the Yemeni forces and the mercenaries of Hadi near an air defense base in northwestern parts of Taiz.

According to the Yemeni Defense Ministry, a number of other mercenaries were also killed in missile attacks by the country's army and Popular Committees east of Marib.

The attacks against Saudi mercenaries came in retaliation for the continued massacre of civilians and destruction of Yemen’s infrastructure by a coalition led by the Saudi regime.

Yemen’s defenseless people have been under massive attacks by the coalition for more than two 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 Hadi.

Over 12,000 Yemenis, including thousands of women and children, have lost their lives in the deadly military campaign.
