Saudi Arabia says heavy cross-border fire from Yemen's Shiite rebels has killed a senior border guard commander and a soldier.

Interior Ministry spokesman Maj. Gen. Mansour al-Turki was quoted by the official Saudi Press Agency as saying that a soldier and Colonel Hassan Ghashoum Aqyli, commander of the Harth border sector in Jizan province were both killed by heavy fire coming from inside Yemen. Four other soldiers were also injured, he added.

Such cross-border firing and shelling have been common since a Saudi-led coalition began a campaign of airstrikes in March against Yemen's Shiite rebels, known as Houthis. Saudi, Emirati and other allied ground troops now are trying to retake Yemen's rebel-held capital, Sanaa.
