Riyadh, March 30 (IANS): Saudi Arabia said on Sunday that all ballistic missiles of Yemen's Houthi rebels will be destroyed in the coming days, Xinhua reported citing Al Arabiya News.

Warplanes of the Saudi-led 10-state coalition raided Yemen's capital Sanaa on Sunday, as the "Decisive Storm" military operation in Yemen against the Shia Houthi group entered the fourth day.

The Saudi-led coalition continued targeting Houthi missile arsenal, according to the spokesperson of the military operation in Yemen, Ahmed Al-Asiri.

"We are working around-the-clock to achieve the goals in the shortest time," he said, stressing that the Saudi borders are secure and far from threats.

On Sunday, air raids targeted the missile arsenal, air defence forces, ammunition warehouses and supply routes of the Houthi militias near the Saudi Arabian border, Al-Asiri said.

The Houthi groups were moving missiles within civilian houses, said Al-Asiri, adding that there were no secure places for the Houthis as they were being heavily targeted in north Yemen and helicopters had destroyed their camps near the Saudi border.

The spokesperson announced on Saturday the success of the first phase of military operations against the Houthis.

In the face of the worsening security situation in Yemen, the Arab League on Sunday called for the establishment of a voluntary, unified military force that member states could turn to when facing challenges to their security.
