At the Assyrian Catholic Church of the East on 35th Avenue in west Phoenix, hundreds of Iraqi dissidents also celebrated, pouring out of the traditional Sunday morning Mass waving Assyrian flags, singing the praises of President Bush and chanting "Down, down Saddam!" Sam Darmo, one of about 8,000 Assyrian Christians from Iraq living in Phoenix, said that even after Saddam went into hiding, many Iraqis continued to fear that he could somehow return to power. [...] he should be tried by the international community for crimes he committed internationally, said Darmo, who is also the Arizona spokesman for the Assyrian Democratic Movement, a major political party in Iraq.
