In Chimkent on March 2, a person engaged in the circulation of Hizb ut-Tahrir leaflets was sentenced to three years in prison.
Hizb ut-Tahrir (the Islamic Freedom Party) was established in 1953 in Jerusalem by Appellation Court judge Takiuddin an-Nabhadi.
After his death in December 1977 Palestinian Abdulkarim Zallum, residing in Jordan, became the amir (leader) of Hizb ut-Tahrir.
The end goal of Hizb ut-Tahrir is the creation of the Islamic caliphate - a theocratic state like the state of the first caliphs existing at the dawn of Islam -- in the territory of the former Soviet Central Asian republics.
