The Saudi forces in the southern border city of Dhahran destroyed Friday missile launch pads in Yemen.

This came after the Saudi forces intercepted military shells fired from Yemen against a Saudi camp, killing a sergeant and two soldiers, a military source said.

Seven soldiers were also injured in the Yemeni attack, the source added.

A coalition of Arab states has been bombarding Houthi militias and their allied army from supporters of Yemeni deposed president Ali Abdullah Saleh since late March in a bid to reinstate President Abd Rabbu Mansour Hadi, who fled to Riyadh.
