Following the attacks early this morning in Belgium, ISIS claimed responsibility for the attacks.
But they didn't just say it was over — different messages obtained from different sources connected to ISIS seemed to say a new round of terror attacks could be on the way.
ISIS's six word warning, as reported by CNN: "What will be coming is worse."
The statement said, "We promise the Crusader allies against the Islamic state, there will be dark days in response to their aggression against our state."
It is clear that, to ISIS, this is a religious war — the forces of the Islamic State against the Christian Crusaders.
