Libyan authorities on Thursday released 87 jailed activists from the Muslim Brotherhood group, all that were in custody, in an apparent gesture of conciliation toward the banned fundamentalist movement, a top Libyan official said. "They are free now and were sent home," said the official on condition of anonymity because he is not authorized to talk to the press. He said they were released from Abu Slim prison, a desert detention center where anti-regime activists have been held. Most of the activists had been in jail since the 1990s. There were no other details about the release or the reasons for they were set free.
