Story:
Yemen’s oppositionists allege that a five-year-old military campaign launched against them has been orchestrated by Saudi Arabia.

An opposition official, Yahya al-Houthi, said on Saturday that Saudi Arabia has gone so far as to deploy warplanes to Yemen to bomb opposition strongholds, Fars News reported.

“In 2004 [Yemeni] President Ali Abdullah Saleh attacked our brothers with the help of Saudi Arabia. Saudi warplanes were used in that strike,” he said.

Al-Houthi said that the same practice has been used in Sanaa’s ongoing crackdown on Shia groups which was launched on Monday in the northern areas of Yemen.
