Members and supporters of Hizb ut-Tahrir in Chittagong organized a demonstration today against the US military exercise ‘Tiger Shark 3'. They chanted slogans that the United States is an enemy state and called upon the Muslims to raise their voice against the exercise. Indeed the US works round the clock to subvert the interests of the Islamic Ummah. This joint exercise and other so-called security cooperation are nothing less than a malicious design by America to implement her strategic design for the region. On top of that America is relentless in her crusade against the rise of Islam in the world including this region. Thus American presence in the region is part of her design to prevent the rise of Islam and delay the re-establishment of the Khilafah "Caliphate". America knows very well that the return of the Khilafah "Caliphate" would be the beginning of her end - the end of her crusade against the Muslims and her dominion in the world. The people participating in the demonstration called upon the Muslims to protest against the government's subservience to America and to work for the re-establishment of the Khilafah "Caliphate".
