Press TV - Yemeni army soldiers, backed by allied fighters from Popular Committees, have reportedly launched an airstrike against a position of Saudi-sponsored militiamen loyal to�Yemen's former president, Abd Rabbuh Mansur Hadi, in the country�s central�province of al-Bayda.

A Yemeni military source, speaking on condition of anonymity, said Yemeni soldiers and their allies attacked Saudi mercenaries in the al-Jaribat�area of the al-Bayda district after they had carried out�aerial reconnaissance�by an unmanned aerial vehicle.

Later in the day, Yemeni troopers and Popular Committees fighters fired a domestically-designed and �manufactured Zelzal-1�(Earthquake-1) ballistic missile at the gatherings of Saudi soldiers in Na�shaw military base of the kingdom�s southwestern border region of Jizan.

There were no immediate reports about possible casualties or the extent of damage caused.

On Sunday evening, Yemeni soldiers and their allies launched another Zelzal-1 missile at Hisn al-Hammad military base in Saudi Arabia�s southwestern region of Najran, leaving a number of Saudi troopers killed and injured and their military vehicles destroyed.

Yemeni snipers, supported by allied fighters from Popular Committees, also fatally shot three Saudi soldiers at al-Shabakah military base in the same Saudi border region.

A further Zelzal-1 missile targeted Saudi forces stated at Hamiyah base in Jizan.

Separately, Saudi fighter jets carried out three airstrikes against an area in the Harf Sufyan district of the northwestern�Yemeni province of �Amran. No reports of casualties were quickly available though.

A civilian also sustained critical gunshot wounds when Saudi border guards fired shots at al-Raqou area in the Monabbih district of Yemen�s mountainous northwestern province of Sa�ada.

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 government of Hadi�back to power and crushing the country�s popular Houthi Ansarullah movement.

The aggression�has killed some�15,000 people and injured thousands more.

More than 2,200 others have died of cholera, and the crisis has triggered what the United Nations has described as the world's worst humanitarian disaster.
