Yemeni army backed by Popular Committees fired a ballistic missile toward southern Saudi Arabia on Wednesday

Yemeni army backed by Popular Committees fired a ballistic missile toward southern Saudi Arabia on Wednesday, a day after four Saudi soldiers were killed on the border with the Arab impoverished country.

"The Yemeni army fired a Scud ballistic missile toward Jizan," Al Maseera TV reported on its twitter page.

Yemen has been since March 26 under brutal aggression by Saudi-led coalition. Thousands have been martyred and injured in the attack, with the vast majority of them are civilians.

Riyadh launched the attack on Yemen in a bid to restore power to fugitive president Abd Rabbu Mansour Hadi who is a close ally to Saudi Arabia.

However, Yemeni army, backed by popular committees and tribal fighter has been responding to the aggression by targeting several Saudi border military posts and cleansing several areas across the country, especially the country’s south, from Hadi and al-Qaeda-linked militias.

Earlier on Tuesday, Riyadh said that three of its soldiers were killed by artillery fire from Yemen, and another died when his patrol vehicle crashed along the border.

A Saudi border post in the kingdom's southern region of Jazan came under shell and rocket fire from Yemeni territory on Monday.

Another soldier operating along the border with Yemen was killed in another incident, the official SPA news agency said.

Earlier on Sunday, Saudi Arabia said that rocket fire had killed a general, the highest-ranking officer to die in cross-border attacks since a Saudi-led coalition began the brutal offensive on Yemen.
