Four Saudi security forces killed by gunmen in southern province

RIYADH - 20 April 2018: Four members of Saudi Arabia's security forces were killed and four others wounded in clashes with gunmen on Thursday at a checkpoint in the southwestern Asir province, Saudi-owned Al Arabiya TV said.

One gunman was killed and two detained, the broadcaster said on Twitter, citing the Saudi interior ministry, without providing more details.

Asir province borders Yemen, where a Saudi-led coalition is battling the armed Houthi group, but it was not immediately clear if the incident was related to that three-year-old war.
