N Korea tests missile as Seoul, US start drills
North Korean leader Kim Jong Un visited a navy unit and oversaw a strategic cruise missile test, state media reported on Monday, ahead of the start of joint military drills between Seoul and Washington.  Kim inspected one of his fleets and watched as the crew staged a drill launching "strategic cruise missiles", state-run news agency KCNA reported.  The drill "aimed to reconfirm the combat function of the ship and the feature of its missile system and make the seamen skilled at carrying out the attack mission in actual war," the report said.  It did not say when the visit took place, or give further details on the types of missiles launched – though it said they "rapidly hit target without even an error".  But Seoul said the KCNA report was "exaggerated and contained many discrepancies from the truth".  "Both South Korea and the United States had been monitoring any related signs – which we detected in advance – in real-time," Seoul's Joint Chiefs of Staff said in a statement. North Korea's announcement came as the annual Ulchi Freedom Shield drills, a major joint exercise between Seoul and Washington, kicked off on Monday.  The exercises, which are aimed at countering growing threats from the nuclear-armed North, will run through August 31.  Pyongyang views all such exercises as rehearsals for an invasion and has repeatedly warned it would take "overwhelming" action in response to the drills.  Suspected North Korean hackers have already targeted the exercises, with email attacks on South Korean contractors working at the allies' combined exercise war simulation centre, police have said.
