An unknown extremist group claimed a December blast in Athens that injured two people outside a church and warned of more to come, a police source said Saturday.
The "Iconoclastic Sect" made its claim in Greek on a Spanish website, saying: "Our hands will not tremble when the time comes to spill blood."
"This act is an introduction to what will follow," the group warned, before hailing "individualists who are at war in the United States and Europe."
