Uzbekistan, hit recently by terrorist attacks, rebuked a group of European nations on Tuesday for allegedly allowing extremists to openly operate on their soil, the Foreign Ministry said. Meanwhile, more than 40 suspects went on trial Tuesday in the capital, Tashkent, and the central city of Bukhara in connection with deadly attacks earlier this year that authorities blamed on Islamic extremists, court officials said. Uzbekistan is concerned that extremist groups are being allowed to openly operate in some Organization for Security and Cooperation in Europe member countries, Foreign Minister Sadyk Safayev told visiting OSCE Secretary General Jan Kubis, according to a Foreign Ministry statement. \"It was pointed out that there are some differences between (Uzbekistan) and the international community in viewing and handling the problem of terrorism and religious extremism,\" the statement said. Uzbekistan was hit by two waves of violence earlier this year that killed more than 50 people and included assaults on police and suicide bombings on the U.S. and Israeli embassies. Authorities said the attacks were carried out by al-Qaida-linked extremist groups operating from outside the country. However, government critics say the violence could have been retaliation by Islamic radicals for the government\'s jailing of thousands of dissident Muslims. President Islam Karimov has long faced strong international criticism for his government\'s poor human rights record, including use of torture in prisons. Last month, Karimov criticized the British government for \"ignoring\" the threat represented by the radical Islamic Hizb-ut-Tahrir party, which he blames for the attacks. The group is allowed to operate in Britain. Hizb-ut-Tahrir, which calls for the establishment of a worldwide Islamic state through nonviolent means, has denied responsibility for the attacks. (AP)
