THE United Nations secretary-general Antonio Guterres warned world leaders today 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 said as the UN general assembly’s annual summit meeting began.

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