1st UPDATE: 6:52 p.m. EDT: If the news is true, there is terrible irony at work; it was just today that Col. Qaddafi called for new talks with NATO about the ongoing civil war in his country. Of course, Qaddafi insisted he would not leave Libya, and that demand likely would have been seen as a non-starter by the United Nations and the West.
2nd UPDATE: 7:13 p.m. EDT: The Associated Press provides additional details on the death of Qaddafi's son. What is perhaps most telling about this report is that the missile attack could have killed Qaddafi:
Qaddafii and his wife were in the Tripoli house of his 29-year-old son, Saif al-Arab Qaddafi, when it was hit by at least one missile fired by a NATO warplane, according to Livbyan spokesman Moussa Ibrahim.
The one-story house in a Tripoli residential neighborhood was heavily damaged.
Saif al-Arab Qaddafi was the sixth son of Qaddafi. He had spent much of his time in Germany in recent years.3rd UPDATE: 7:31 p.m. EDT: The Washington Post has posted photos of the home that was hit by an airstrike.
