The last night attacks reflect how despite three months of Saudi-led airstrikes targeting the rebels known as Houthis, the rebels are still capable of launching deadly attacks along the kingdom's border.
The Saudi Press Agency carried a military statement today, saying that two soldiers died in the border region of Najran, while the third died in the region of Asir.
Houthis frequently fire missiles from inside Yemen at Saudi border posts. More than two dozen Saudi soldiers have been killed in such attacks.
