OSLO/GENEVA—The Norwegian Nobel Committee, warning of a rising risk of nuclear war and the spread of weapons to North Korea, awarded the 2017 Nobel Peace Prize on Friday to a little-known campaign group seeking a global ban on nuclear arms.
The award for the International Campaign to Abolish Nuclear Weapons (ICAN) was unexpected, particularly in a year when the architects of the 2015 nuclear deal between international powers and Iran had been seen as favorites for achieving the sort of diplomatic breakthrough that has won the prize in the past.
