The six countries that make up the Gulf Cooperation Council are vital regional and international players.
They are Saudi Arabia, Qatar, the United Arab Emirates, Oman, Kuwait and Bahrain. When their leaders hold an annual summit, it makes news around the world.
But this year, Al Jazeera was banned from covering the summit in the Bahrain capital of Manama, despite submitting the required paperwork in time.
In a statement, Al Jazeera condemned the measure, saying it's a "deviation from the normal media protocols of host countries".
The network has affirmed that it will continue to cover news and events in Bahrain regardless of the ban.
But why was Al Jazeera singled out? And should there be a common rule for journalists covering international events?
