A fake news story in late May 2017 triggered a major diplomatic crisis in the Gulf.

The story was planted on the website of Qatar News Agency (QNA) by hackers. It falsely attributed comments to Qatar's emir, which were then aired on Saudi-owned Al Arabiya channel.

A few weeks later, in early June, Saudi Arabia, the United Arab Emirates (UAE), Bahrain and Egypt severed all ties with Qatar. 

As British media watchdog Ofcom investigates Qatar's complaint against Al Arabiya for the false story, the Dubai-based channel has surrendered its license to broadcast in the United Kingdom and the European Union. 

QNA says Al Arabiya's decision was dictated by the inquiry but the channel says business reasons influenced the step.

Currently in its ninth month and affecting people across the region, the crisis highlights the dangers posed by fake news.

What can be done to stop fake news? Should states intervene, or should journalists regulate themselves? And what is the role of tech companies?
