Saudi Arabia, Egypt, Bahrain, the United Arab Emirates and Yemen have cut diplomatic ties with Qatar.
But what might this mean for Qatar’s economy and people doing business there?
With a population of about 2.7 million people, this tiny nation on the north-east coast of the Arabian Peninsula is trying to punch above its weight.
People know about it thanks in part to its national airline (Qatar Airways), its international news station (Al Jazeera) and through sport (notably winning the 2022 football World Cup and being a former sponsor of perhaps the world’s most famous club, Barcelona).
And with a distinctive skyline in the capital Doha, it has succeeded in attracting multinationals to open offices there.
