Star-studded Saudi exhibition postponed after deadly attacks

The Six Kings Slam tennis exhibition event in Saudi Arabia - featuring Grand Slam champions Carlos Alcaraz, Novak Djokovic and Alexander Zverev - has been postponed following a series of deadly attacks on host city Riyadh.

Alcaraz, Djokovic and Zverev were set to travel to the Saudi capital for a three-day event starting on 21 October.

Australia's Alex de Minaur, along with American pair Taylor Fritz and Learner Tien, were also earmarked to play.

The event had been in serious doubt since Yemen's Houthi movement launched attacks on Saudi Arabia at the weekend, including a missile strike on Riyadh's airport on Saturday that killed 13 people and wounded more than 300.
