Press TV - Scores of Saudi soldiers and Saudi-sponsored militiamen loyal to Yemen's former president Abd Rabbuh Mansur Hadi have lost their lives when Yemeni army soldiers and fighters from allied Popular Committees launched separate offensives against their positions in the kingdom’s border regions.

Yemeni troops and their allies fired three domestically-developed missiles at the gatherings of Saudi troopers and their mercenaries in al-Khobe district of the kingdom’s Jizan region, located 966 kilometers (600 miles) south of the Saudi capital, Riyadh, on Wednesday evening, leaving several of them dead or injured.

Several Saudi soldiers and Saudi-backed militiamen were also killed and injured, when Yemeni troops and fighters from Popular Committees targeted their camps west of al-Majazah area and near al-Alab border crossing in Asir region with a barrage of Katyusha rockets and artillery rounds.

Later in the day, Saudi missiles and mortar shells rained down on residential areas in the Baqim district of Yemen’s northwestern province of Sa’ada.

There were, however, no immediate reports of possible casualties and the extent of damage caused.

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 Ansarullah movement.

Some 15,000 Yemenis have been killed and thousands more injured since the onset of the Saudi-led aggression.

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.
