Shelling from Yemen has killed a Saudi soldier on the kingdom's southern border, the interior ministry said Sunday.
A Border Guards post in Najran region came under attack from "intensive shelling" at 5:00 pm (1400 GMT) Saturday, killing a corporal, the ministry said.
Army troops intervened to support the Border Guards.
The corporal is the latest of more than 110 soldiers and civilians killed in southern Saudi Arabia by rocket strikes or skirmishes since a Saudi-led coalition began operations in Yemen almost two years ago.
In support of President Abedrabbo Mansour Hadi's government, the alliance started air strikes after Huthi rebels and their allies overran the capital Sanaa and moved on to other parts of Yemen.
Since then, more than 7,400 people have been killed in Yemen, where United Nations mediation and seven ceasefires have failed to stop the fighting.
