Saudi Arabia has shot down a Scud missile fired from across the border by Yemen's Houthi rebels and its allies, the state Saudi Press Agency says.

It was intercepted by a Patriot missile battery near the south-western city of Khamis Mushait in the morning.

On Friday, four Saudi soldiers and many Yemeni rebels died in fighting on the border, the Saudi-led coalition says.

It says forces loyal to Yemen's former president, backed by the Houthis, attacked several Saudi positions.

In a separate development, the Houthis have agreed to attend peace talks in Geneva.

The UN-brokered meeting on 14 June in Switzerland is aimed at ending weeks of war that has claimed more than 2,000 lives.
