In the light of the cowardly attack on the Muharram procession on Karachi's M A Jinnah road on Monday 28 December, killing at least 40 Muslims and wounding dozens, Hizb ut-Tahrir  Wilayah Pakistan held nationwide demonstrations and sent delegation to Imambaragh in the country. Hizb ut-Tahrir  strongly denounced the relentless campaign of bombings, funded and organized by America's agencies and private military organizations, such as Xe Services LLC (formerly known as Blackwater). Hizb ut-Tahrir  condemned America's brutal tactics, which she has employed in Afghanistan and Iraq, and called for the immediate establishment of the Khilafah "Caliphate", which will unify the Muslims of the world and remove all colonialist presence from the Muslim Lands.
