Yemeni forces launched a Scud missile at a missile base in Saudi Arabia on Tuesday, Yemeni state news agency Saba quoted the military's spokesman as saying.

"The rocket units in our heroic armed forces today launched a Scud missile at the Al Sulayyil missile base in Riyadh province ... it comes as a response to the crimes of the brutal Saudi aggression," Brigadier General Sharaf Luqman said.

Saudi Arabia had earlier this month reported that it had shot down a Scud missile fired into the kingdom by Houthis, in the first use of the missile in over two months of war.

The missile was launched in the direction of Khamees Al Mushait, and was intercepted by a Patriot missile. The area is home to largest air force base in southern Saudi Arabia, the world's top oil exporter, but there are no oil facilities in the area.

An alliance of Gulf nations has been bombing Yemen's dominant Houthi militia and allied army units loyal to powerful ex-President Saleh since March 26 in an attempt to restore exiled President Abd-Rabbu Mansour Hadi to power.

The coalition has said a main goal of their war effort is to neutralise the threat that rockets in Yemen pose to Saudi Arabia and its neighbours.-Reuters
