From ballistic missiles to unmanned drones, Yemen's Huthi rebels appear to have bolstered their fighting capabilities, posing a serious threat to mighty neighbour Saudi Arabia.
In June alone, the Iran-aligned Shiite Huthis launched at least 20
missile and drone attacks on the oil-rich kingdom, Iran's regional foe, some resulting in casualties and damage.
Saudi advanced air defences successfully intercepted most of the strikes but failed to deal with some, including a drone attack on the vital airport of Abha, in the south, that killed one person and injured 21 others.
