A Saudi soldier has been killed in shelling on the border with Yemen, the military said late Wednesday, adding to a rising toll in the kingdom’s south over the past week.

The Yemeni air defense forces downed a Saudi Apache helicopter gunship on Wednesday with a surface-to-air missile in the district of Harad in Hajjah.

In similar achievement, a Saudi soldier has been killed in shelling on the border with Yemen, the military said late Wednesday, adding to a rising toll in the kingdom's south over the past week.

"He was hit by a projectile in the sector of Jazan," a Saudi border district, said a statement from the Saudi-led coalition which has been bombing Yemen for more than four months in support of fugitive President Abedrabbo Mansour Hadi.

The army attack came in retaliation for the continuous Saudi-US war on the country that killed so far more than 4000 people, and caused much destruction across provinces.

In Friday rocket fire from Yemen by the national army and the Popular Committees killed three soldiers and a paramilitary along the frontier, in the deadliest such incident for several weeks.

The airstrikes have so far claimed the lives of more than 5,302 civilians, mostly women and children.
