Saudi Arabia assembles 'massive force' on Yemen border

Saudi Arabia has assembled a "massive" additional force on its border with Yemen after trading heavy artillery and rocket fire with Yemen's Houthi fighters, a day before a proposed truce takes effect. Al Jazeera's Mohamed Vall, reporting from Riyadh, said Saudi Arabia's defence ministry announced on Monday that a "massive" force had reached Najran on its way to taking its position on the frontlines adjacent to Yemeni territory, following Monday's exchange of fire.
