Saudi “strike force” posted on Yemen border

Saudi Arabia is sending a "strike force" to its border with Yemen after the villages of Najran came under heavy mortar shelling by Yemeni Houthi rebels, causing civilian casualties. The Saudi-owned Al Arabiya Hadath TV channel broadcast pictures of a column of tanks loaded onto military trucks and described it as "the arrival of reinforcements from the strike force to the border.”  The five-day humanitarian ceasefire declared by Saudi Arabia and approved by the Yemeni rebels is due to go into force Tuesday night.
