Muammar Gaddafi's son Hannibal fled to Algeria after the 2011 fall of Tripoli. He moved on to Oman, then Syria, where he was kidnapped by members of the Amal Movement, a Shia-linked Lebanese political party, as retribution for the decades-ago Libyan disappearance of its founding imam Moussa al-Sadr. Hannibal is in Lebanon, not allowed to leave.
