Saudi stocks fell sharply on Sunday, after attacks on two plants at the heart of the kingdom's oil industry a day earlier knocked out more than half of Saudi crude output. Sunday's decline extended a losing spree for Saudi stocks, which in recent weeks have been hit by expensive valuations, weak oil prices and concerns about the economic outlook.
The drone attacks were carried out by Yemen's Houthi group, its military spokesman said on Al Masirah TV.
The index opened down 2.3% but later pared some losses.
