ISLAMABAD, Pakistan- Pakistani intelligence agents found plans for new attacks against the United States and Britain on a computer seized during the arrest of a senior Al-Qaida suspect wanted for the 1998 twin U.S. embassy bombings in East Africa, the information minister said.
The plans were found in e-mails on the computer of Ahmed Khalfan Ghailani, a Tanzanian arrested July 25 after a 12-hour gunbattle in the eastern city of Gujrat, Information Minister Sheikh Rashid Ahmed told The Associated Press on Monday.
"We got a few e-mails from Ghailani's computer about [plans for] attacks in the U.S. and U.K.," he said.
Ahmed said authorities have also arrested another top Al-Qaida suspect believed to be a computer and communications expert, and that that man was cooperating with investigators.
"He is a very wanted man, but I cannot say his name now," Ahmed said.
Interior Minister Faisal Saleh Hayyat confirmed that Ghailani was sharing "vital" information, but he would not comment on what it was.
"He has given us vital information, but we cannot share specifics," Hayyat said. An intelligence official said the information about a U.S. attack appeared to be centered on New York. He spoke on condition of anonymity.
