Yemen’s official news agency Saba said on Saturday that three Saudi soldiers were targeted by snipers in Borj ul-Dud military camp in the al-Tawwal district of Saudi Arabia’s southern province of Jizan.
The report said one more Saudi officer was killed while on duty in al-Ramadhah camp in the same region.
Houthis say the attacks on the Saudi military positions are in reprisal for Riyadh’s airstrikes on Yemen.
The deadly Saudi campaign against Yemen has killed nearly 8,300 people since March 26, 2015.
Dozens of Saudi soldiers and high-ranking officers have been killed in the retaliatory attacks over the past months. Yemeni forces have also clashed with troops from Saudi Arabia, the United Arab Emirates and Bahrain, as well as mercenaries Riyadh has recruited.
Saba said Yemeni forces also launched rocket attacks on Saturday on military positions south of Saudi Arabia, including on a number of bases in the provinces of Najran and Jizan.
Yemenis also fired Zelzal missiles on other posts, with no immediate reports available on the potential casualties among the Saudis, the report said.
The Saudi airstrikes have been meant to undermine Ansarullah and bring Yemen’s fugitive former President Abd Rabbuh Mansur Hadi back to power.
The Saudi campaign has also taken a heavy toll on Yemen’s infrastructure, destroying many hospitals, schools, and factories across the impoverished country.
Saudi warplanes carried out a combat sortie against Yemen’s northwestern province of Sa’ada on Saturday. Nearly a dozen civilians were injured. Saudi jets also hit a number of residential neighborhoods in the Dhahyan district of the same province.
