Yemen's army on the offensive with advanced drones

Over the past few months, Yemen’s Ansarullah movement has intensified its retaliatory attacks against Saudi Arabia. On Monday, the movement announced it had targeted a military site in the Saudi capital, Riyadh with armed drones. It marks the first time in a year that Ansarullah has said it has targeted Riyadh.The Kingdom has denied the attack took place saying it brought down a drone in Yemeni airspace. This comes one day after a military spokesman for Ansarullah said the movement had fired ten short-range ballistic missiles at Saudi Arabia's southwestern Jizan airport.
