As in the title, have they have made legitimate justifications based on tangible evidence or its mainly another excuse for something that they've done in the past as well? To my understanding Saudi Arabia isnt any less sympathetic and/or funding terrorists(maybe not the same ones but terrorists regardless) less than Qatar. Edit: To clarify, im not asking how this move fits the Saudi Arabian Agenda but I am asking if Saudi Arabia had anything new to show for their claims or if its just vague generalization to press forward with it.
Yes, they have official justification.
As per one of the news articles on the topic:
A HUGE ransom paid to secure the release of kidnapped members of the Qatar Royal family was the final trigger which sparked Saudi Arabia and others to sever ties with the isolated nation.
The ransom, which was around $1 billion, was believed to have been paid to militias with close ties to Tehran, the Financial Times has revealed.
The news comes as non-profit policy organisation the Counter Extremism Project revealed the full extent of how Qatar has been financing and harbouring a dozen terrorists and operatives who have been living freely — and in some cases, in luxury — within oil-rich Qatar.
Among others, Quatar was a long time home base for Muslim Brotherhood and its offshoot, Hamas, terrorists.
