Tough talk to North Korea from the country's neighbor to the South following the launch of another North Korean missile.
FOX's Simon Owen reports:
South Korea out today with what it called a strong warning to North...
The South conducting a live-fire exercise simulating an attack on North Korea's main nuclear site. The South Korean defense ministry also saying it's continuing to see signs of preparations for further North Korean missile launches.
There've already been 13 this year to date and over the weekend North Korea conducted its sixth nuclear test explosion believed to be its largest yet.
North Korea claiming the test was a perfect success.
