The diplomatic crisis in the Gulf Cooperation Council (GCC) has taken another turn. The Washington Post reported Sunday that the U.S. intelligence community had information suggesting the United Arab Emirates arranged a cyberattack on Qatar's state news agency in late May that set the dispute in motion. Unnamed U.S. intelligence officials claimed that Abu Dhabi orchestrated a breach of the Qatar News Agency's website and social media accounts to post erroneous statements from Qatari Emir Sheikh Tamim bin Hamad al-Thani expressing support for Iran, Hamas and Hezbollah. The United Arab Emirates, along with Saudi Arabia, Bahrain and Egypt, then used the false quotes as a pretext to sever diplomatic and economic ties with Qatar. The revelation doubtless will further complicate relations in and beyond the GCC. At the same time, however, it's hardly a surprise.
