Asian markets, won, sink after nuclear test

HONG KONG: Asian and European stocks tumbled along with the South Korean won Monday while the safe-haven yen rallied on news that North Korea had tested what it claimed was a hydrogen bomb, ramping up international tensions.

Less than a week after it rattled global markets by firing a rocket over Japan, Pyongyang on Sunday conducted its sixth nuclear test -- sparking further condemnation and a warning from US Defense Secretary Jim Mattis of a “massive military response” if the US or its allies were attacked.
