The Silco incident involves the kidnapping of the Belgian-French family Houtekins-Kets by the Libyan government from their yacht Silco in the waters of the Mediterranean Sea on August 1, 1985. The Belgian part of the family was held for almost five years of captivity in Libya, but were freed after the release of Said Al Nasr (who was convicted in the early 1980s for throwing a hand grenade into a group of Jewish children in Antwerp in the 1980 Antwerp summer camp attack) for the family, in Cairo, Egypt, on January 12, 1991. The French part of the family were released somewhat earlier, when the French government negotiated their freedom with the Libyan government.
