The Iran war, now in its third week, is already proving costly: on Friday, a Trump administration official said the conflict had so far cost $12 billion (€10.4bn), or just under $1 billion a day.
Iran has reacted to the US-Israeli intervention by launching its own bombardment campaign against its regional neighbours, using cheap drones like the Tehran-designed and made Shahed 136, costing $20,000-50,000 each (€17,400-€43,500).
