Saudi Arabia extends airport closure as Houthis warn 'worse is yet to come'

Key points

• Yemen's Houthis have warned airlines, travellers and airport workers to avoid Saudi airports, a day after an attack on Riyadh's international airport killed 12 people and wounded more than 300. It was the deadliest such attack in the kingdom in more than a decade.
• Saudi Arabia extended the airport closure until at least 9pm on Sunday, local time. The Houthis said further Saudi military action in Yemen would bring a stronger response, warning that worse is yet to come.
• Condemnations came from Arab countries, the United Nations and European leaders.
