Kim Jong Un's sister warns S Korea over drills

The powerful sister of North Korea's leader Kim Jong Un on Tuesday strongly criticised South Korea for proceeding with military exercises with the United States. Kim Yo Jong said the exercises were an invasion rehearsal and warned that the North will work faster to strengthen its preemptive strike capabilities.  Her statement came after South Korean media reported the allied militaries will begin four days of preliminary training on Tuesday before holding computer-simulated drills from August 16 to August 26.
