LAGOS: A spokesman for the militant Boko Haram group in Nigeria has told Bikyamasr.com the group is to call for an increase in attacks against American interests over the anti-Islam film that sparked widespread protests across the Islamic world. “We will be firm in our belief that nobody can attack our faith and we hold the US responsible for the film,” a spokesman said via telephone on Wednesday. It comes as protests have largely calmed across the Islamic world, including here in Nigeria, after the film allegedly produced by a Coptic Christian man living in California created widespread anger for insulting and defaming Islam and Prophet Mohamed. “Muslims should rise up and fight against these attacks against our great faith and the Prophet. We are going to call on our followers to attack American interests wherever they are found, including citizens,” the spokesman continued. “Islam is a faith of strength and if we remain weak and allow these attacks to take place, the west will continue to insult us and call us names,” he added. Across the Muslim world, there have been numerous calls for calm and for Muslims not to engage in violence over the film.
