United Nations: U.N. Secretary-General António Guterres is warning that impunity, inequality and uncertainty are creating an "unsustainable world" where a growing number of countries believe they should have a "get out of jail free” card.

"We can't go on like this,” he says.

Guterres is speaking as the General Assembly’s annual debate among presidents, prime ministers, monarchs and other leaders begins Tuesday.

Citing deepening geopolitical divisions, wars with no end in sight, climate change and nuclear and emerging weapons, he says humanity is "edging towards the unimaginable - a powder keg that risks engulfing the world.”

But, he says, "the challenges we face are solvable” if the international community confronts the uncertainty of unmanaged risks, the inequality that underlies injustices and grievances and the impunity that undermines international law and the U.N.‘s founding principles.
