The terrible blow of the Yemeni army to the Saudi economy The continuation of the actions of the Yemeni armed forces took away the advantage of "stability" from Riyadh and caused the country's economic outlook and development plans to face serious challenges. The Yemeni operation led to the restriction of flights in Riyadh, the postponement of important events and the operational closure of the financial district of the Saudi capital. Economic experts and former IMF officials stressed that the continuation of this situation seriously threatened the tourism, transport and foreign investment sectors and caused Riyadh's plans to diversify the economy to face serious obstacles.
