According to Yemeni News Agency (Saba), during the Saturday operation in Talaa near Najran some military cars were also destroyed.
Saudi news agency also confirmed that four forces were killed and released their names.
Yemeni snipers also killed a Saudi military man in Najran on Friday.
The Yemeni artillery unit and popular committee in an operation inflicted heave damage on Saudi forces in Jizan and Najran.
Earlier President of the Supreme Revolutionary Committee of Yemen Mohammad Ali Al-Houthi said that invaders are doomed to failure in their attempts to rage war in Yemen’s west coast region.
“As previous escalation of the aggression in the West Coast failed, their current escalation will fail too,” he added.
Saudi Arabia and its regional allies attacked Yemen in March 2015 to bring back to power the deposed president of Yemen Abdrabbuh Mansour Hadi.
The aggressors have committed horrible war crimes against Yemeni civilians during the past three years.
