In the e-mail sent by "al-wilayat al-Islamiyya Gharb Afriqiyyah" on Friday, the group said it is attacking UI for "shamelessly" spreading Western education among Africans.
A copy of the letter obtained by journalist Ademola Babalola in Ibadan stated:
"You people are an embarrassment to Nigeria and are the people that brought in western education to Nigeria. You doomed this nation and in turn you all are going to be doomed.
"Most of you are going to die before Independence day. You will not spend the independence day in peace, you and your students.
"Detonation will start g from tomorrow till independence day and there is nothing you can do as we are among you. Even your little searches at the gate won’t do anything. By the time we are through with you, your government will be sorry."
