World News Australia - Australian Coptics protest persecution
More than 500 Coptics and their Muslim friends marched in central Sydney, calling on Prime Minister Julia Gillard and Foreign Minister Kevin Rudd to address the issue, after a bomb blast killed 21 people during a New Year's Eve Coptic church service in Alexandria, Egypt.
"We understand that Mr Kevin Rudd and Julia Gillard have not personally issued statements of condemnation," said the spokeswoman, who asked not to be named for safety reasons.
"We don't understand why they're silent and other leaders aren't."
