As you know, Saudi Arabia and Iran currently have a cold war going on, accompanied by proxy wars through out the Middle East. Qatar is a small peninsula sticking out of Saudi Arabia. It is smaller than the Falkland Islands.
In 2017, Qatar and Saudi Arabia had a major falling out.

SA demanded that Qatar shutdown Al-Jazeera and all other news orgs, break off relations with Iran, pay unspecified piles of money that SA got to determine, and "align itself with the other Gulf and Arab countries militarily, politically, socially and economically, as well as on economic matters...".
SA and neighboring countries then closed the land border, and stopped allowing ships to unload cargo and transfer to smaller ships for delivery to Qatar. This affected almost all cargo headed into the country, since Qatar's port can't support large ships.
The neighboring countries also announced that anyone who shows sympathy to Qatar "whether it be through the means of social media, or any type of written, visual or verbal form", would be subject to $130,000 fine and three to fifteen years in jail.
And that's where things have been for the last nine months.

(Qatar, Iran, and SA all fund terrorism and terrorist organizations. There are all busy playing the Middle East version of the game of thrones. Any sympathy I feel for Qatar is because they are one of the little guys in this fight.)
