The Saudi military on Monday said two soldiers have been killed along the border by a missile fired from inside Yemen.
The statement released Monday said the soldiers were killed in the Saudi border region of Jizan.
Saudi Arabia has been leading a coalition of Arab countries in airstrikes against Shiite rebels and their allies in Yemen since March.
Several dozen Saudi soldiers have been killed in border attacks since the airstrikes began, mostly by missiles launched by the Houthi rebels and their allies.
The United Nations says health facilities in Yemen have reported more than 4,000 conflict-related deaths since the coalition began airstrikes.
The Houthis overran Yemen’s capital and other cities last year, forcing the country’s Saudi and US-backed President Abed Rabbo Mansour Hadi into exile in Saudi Arabia.
