The Simon Wiesenthal Center called for an international arrest warrant to be issued for the apprehension of Hamas leader and one of Israel's most wanted men, Khaled Mashaal, according to a press release put out by the organization. According to the SWC, Mashaal is the chief architect in the terror campaign against Israel. "The time has come for the United Nations to demand that Syria give up Khaled Mashaal and to issue an international arrest order for his apprehension," wrote Rabbi Marvin Hier, the Center's Founder and Dean, in a letter to United Nations Secretary General Kofi Annan on Thursday. "He is no less an international pariah and outlaw than Osama Bin-Laden and Ayman al-Zawahiri and should be tried for his crimes against humanity. Mashaal is the real face of Hamas and as long as the international community allows him to live freely and continue his terrorist activities, there will be no road map and no prospects to achieve Middle East peace," added Hier.
