The Dogs of War are barking.

Saudi Arabia’s Crown Prince Mohammed bin Salman has accused Iran of an act of “direct military aggression” by supplying missiles to rebels in Yemen.

This “may be considered an act of war”, state media quoted the prince as telling UK Foreign Secretary Boris Johnson in a telephone conversation.

On Saturday, a ballistic missile was intercepted near the Saudi capital.

Iran has denied arming the Houthi movement, which is fighting a Saudi-led coalition backing Yemen’s government.
