Let's go back to March and the stories that were emerging from the Arab League summit here in Doha:

"Saudi and Qatari delegates were heard hurling shrill abuse at one another and exchanging blows in private meeting rooms down the corridors of the assembly hall. The conference proceedings were abruptly halted as Arab delegation members pitched in to separate them. A total blackout was quickly drawn down on the summit as it broke up in disarray.
Riyadh - and Prince Bandar in particular - accuses the Qataris of conspiring to bring the Muslim Brotherhood to power in Damascus, including radical groups tied to Al Qaeda."
