Iran says accusations by Saudi Arabia and the US that it supplied the missile fired by Yemen's Houthi rebels at Riyadh on Tuesday are "baseless".

A foreign ministry spokesman said Iran had "no arms links with Yemen" and that the country was "in a blockade and such possibility does not exist anyway".

The Saudi military said it intercepted the missile south of Riyadh. There were no reports of any damage or casualties.

The Houthis said they targeted a palace where the Saudi leadership was meeting.

They have been fighting a war against forces loyal to Yemen's President Abdrabbuh Mansour Hadi and a Saudi-led coalition backing him since March 2015. The coalition receives logistical and intelligence support from the US and UK.

The Houthis' Missile Forces announced they fired a Burkan H2 missile at the al-Yamama Palace in Riyadh on Tuesday afternoon "in response to the heinous crimes committed by the US-Saudi aggression against the people of Yemen".

The coalition said the missile was "indiscriminately launched towards Riyadh to target the civilian and populated areas".BBC, YOL
