BRUSSELS – Pope Francis today called for peace, warning politicians in Belgium that a third world war was “very close”.

In an off-the-cuff remark in a speech to civic leaders, the Pope said: “Right now Belgium has a very important role. We are close, almost, to a world war.”

Peace and harmony, he said, are “never won once and for all” but require consistent effort to maintain with care and patience.

“When human beings forget the memory of the past and its valuable lessons, they run the dangerous risk of once again falling backwards, even after having moved on, forgetting the suffering and appalling costs paid by previous generations,” he said.
