Terror in Tashkent

According to Reuters, two female suicide bombers carried out attacks in the Uzbek capital of Tashkent. The Uzbek government is blaming Hizb ut-Tahrir, a non-violent Islamist group banned mainly because they oppose the Uzbek government. My own suspicions fall on the Islamic Movement of Uzbekistan, and group which was essentially crushed during the U.S. invasion of Afghanistan, but seems to have revived and has come up in reports of recent fighting in Pakistan.
