The Bangladesh government says it is investigating the origin of the alleged audio-message by Al-Qaeda chief Ayman al-Zawahiri, State Minister for Home Asaduzzaman Kamal Khan said on Sunday. He told journalsists at the Secretariat that Bangladesh was capable of handling threats posed by such terror groups. Khan said Bangladesh’s law-enforcing agencies were coordinating with international organisations to prevent terrorism. An audio tape said to be carrying a message from Al-Qaeda chief Ayman Al-Zawahiri was circulating on the Internet, calling on Muslims in Bangladesh to start an uprising. It also said the idea of the Bengali nation has not worked out.
