TEHRAN (Press Shia) – Yemen’s artillery units targeted the positions and gatherings of Saudi troops in the kingdom’s southwestern border regions of Najran and Jizan, killing and injuring scores of them.

In Najran, the shelling targeted the Saudi gathering centers in the areas of Manara and Selh while a Saudi military vehicle was destroyed in Boqea desert, a military source, speaking on condition of anonymity, told Saba news agency on Monday.

Also in Najran, the sniper unit of the Yemeni army hunted down Saudi-paid mercenaries in western areas.

In Jizan, the artillery fore of the army pounded Saudi soldiers’ positions in Samnah center and the north of Abidiah site, the report added.

On Friday, Yemeni snipers killed 13 mercenaries in separate operations in the areas of Taiz, Jawf and Sirwah.

Yemen's Ministry of Human Rights said in a statement on March 25 that the ongoing Saudi-led war had left 600,000 civilians dead and injured since it started in March 2015.

The United Nations says a record 22.2 million Yemenis are in need of food aid, including 8.4 million threatened by severe hunger.

A high-ranking UN aid official recently warned against the “catastrophic” living conditions in Yemen, stating that there was a growing risk of famine and cholera there.

“People's lives have continued unraveling. Conflict has escalated since November driving an estimated 100,000 people from their homes,” John Ging, UN director of aid operations, told the UN Security Council on February 27.

Ging said cholera had infected 1.1 million people in Yemen since last April, and a new outbreak of diphtheria had occurred in the war-ravaged Arab country since 1982.
