Maj. Paeta Hess-von Kruedener, a Canadian UNTSO peacekeeper killed in Lebanon overnight Tuesday by an IAF missile strike on his post, wrote in an email to his former commander in the Canadian army six days before he was killed that Hizbullah was using the UN post as a human shield. Kruedener added in the email that IAF strikes near the UN post prior to his death were "necessary" and that the IDF fire was not intentionally targeting the post. Maj.-Gen. Louis Mackenzie, Kruedener's ex-commander, told a Canadian radio station about the email letter in an interview. Kruedener's wife demanded Thursday to know why IAF missiles struck the UN site where her husband was stationed, despite repeated pleas by observers there to halt the firing. Cynthia Hess-von Kruedener told reporters in Kingston, Ontario, that she believes the attack, which involved precision guided missiles, was intentional. Hess-von Kruedener said her husband told her that the UN site had been fired upon for weeks, despite the fact that their vehicles and buildings were clearly marked.
