offered relatives, soldiers, police officers, and social workers free sandwiches, hot meals, beverages, and counseling. The people of the town washed, dried, and ironed every piece of clothing that was found once the police had determined they were of no forensic value, so that as many items as possible could be returned to the relatives. The BBC's Scotland correspondent, Andrew Cassell, reported on the 10th anniversary of the bombing that the townspeople had "opened their homes and hearts" to the relatives, bearing their own losses "stoically and with enormous dignity", and that the bonds forged then continue to this day. Prior alerts Two alerts were released shortly before the bombing. Helsinki warning On 5 December 1988 (16 days prior to the attack), the US Federal Aviation Administration (FAA) issued a security bulletin saying that, on that day, a man with an Arabic accent had telephoned the US Embassy in Helsinki, Finland, and told them that a Pan Am flight from Frankfurt to the United States would be blown up within the next two weeks by someone associated with the Abu Nidal Organization; he said a Finnish woman would carry the bomb on board as an unwitting courier.
