UN nuclear Chief warns of 'unimaginable' destruction without Iran diplomacy

The UN nuclear watchdog chief called for diplomacy and a return to negotiations over Iran's nuclear ambitions. "Otherwise, violence and destruction could reach unimaginable levels, and the global non-proliferation regime that has underpinned international security for more than half a century could crumble and fall," said Rafael Grossi, director of the International Atomic Energy Agency (IAEA). He also called for a cessation of hostilities.
