RIYADH: Rocket fire from war-wracked Yemen on Friday killed threeSaudi soldiers and a member of a paramilitary force, in the deadliest border incident for several weeks, the interior ministry said.
The three soldiers died and seven border guards were wounded as a barrage of rockets crashed into the Asir region, the ministry said in a statement carried by the official Saudi Press Agency.
The army returned fire.
In the neighbouring region of Jazan, a paramilitary fighter was killed and another wounded in shelling from the Yemeni side of the border, the interior ministry said.
The bombardment came during a day of relative calm in Yemen itself, where forces aligned with exiled President Abedrabbo Mansour Hadi are fighting Shiite Huthi rebels.
Government-aligned forces have since last week been expanding their area of control after recapturing the southern port city of Aden.
They are supported by a Saudi-led Arab coalition which launched air strikes on the Huthis in March.
The border barrage came on the final day of what was supposed to be a ceasefire to allow in aid for Yemen's stricken civilians. AFP
