A Saudi-led coalition says it intercepted and destroyed three drones in the south and in Riyadh, as well as two cruise missiles over the Red Sea, according to coalition spokesman Turki al-Maliki.

Riyadh's main international airport remains closed after a deadly strike there last week, and since July the Houthis have repeatedly struck Saudi targets including Red Sea tankers, oil facilities and the capital's airport, where 13 people were killed.
