"A sum of 90 Al-Qaeda terrorists were killed in heavy fighting with army and Ansarullah forces in Ba'er Ahmad region of Aden," Saba news agency quoted an informed Yemeni military source.

The Yemeni army and popular forces are still continuing their mop-up operations in Aden's Ba'er Ahmad region.

The advances by the Yemeni forces came as the Saudi fighter jets are still pounding Aden to prevent further gains by the army and Ansarullah.

Earlier, the Yemeni army and Ansarullah fighters besieged a large number of Al-Qaeda terrorists in the province of Taiz as they continued to advance against the Saudi-backed militants.

Popular forces have tightened the noose on Al-Qaeda terrorists in Be'r Ahmad in Aden.

The Ansarullah fighters and army troops have made major advances in their fight against the Saudi-backed al-Qaeda terrorists and forces loyal to fugitive former President Mansour Hadi across Yemen in recent weeks, FNA reports.

The clashes between the Ansarullah fighters and the Saudi-backed al-Qaeda terrorists as well as the pro-Hadi militias continue in the Southern parts of the country as Saudi Arabia has been striking Yemen for 80 days now to restore power to fugitive president Mansour Hadi, a close ally of Riyadh.

Hadi stepped down in January and refused to reconsider the decision despite calls by Ansarullah revolutionaries of the Houthi movement.

Despite Riyadh's claims that it is bombing the positions of the Ansarullah fighters, Saudi warplanes are flattening residential areas and civilian infrastructures.

The Monarchy's attacks have so far claimed the lives of at least 4,561 civilians, mostly women and children.
