The FT has unveiled what its believes is the key trigger behind the shocking overnight collapse in diplomatic relations between Qatar and its Gulf neighbors. According to the FT, the catalyst that forced the Saudis and their allies to unveil the cut in diplomatic and economic ties, is that Qatar allegedly paid up to $1 billion to Iran and al-Qaeda affiliates "to release members of the Gulf state's royal family who were kidnapped in Iraq while on a hunting trip, according to people involved in the hostage deal"; the secret deal was allegedly one of the triggers behind Gulf states' dramatic decision to cut ties with Doha.

The details of the payoff: "around $700m was paid both to Iranian figures and the regional Shia militias they support, according to regional government officials. They added that $200m to $300m went to Islamist groups in Syria, most of that to Tahrir al-Sham, a group with links to al-Qaeda."
