South Korea says its troops have exchanged gunfire along land border with North Korea and that there are no injuries.

South Korea’s military said its troops exchanged fire with North Korea along their tense land border on Sunday.
The Joint Chiefs of Staff in Seoul said North Korean troops fired several bullets at a South Korean guard post inside the heavily fortified border between the two countries at 7:41 am on Sunday.
South Korea fired two rounds in response after issuing a warning broadcast, the military said in a statement, adding it suffered no casualties.
“We are taking actions via inter-Korean communication lines to grasp the detailed situation and to prevent any further incidents. And we also maintain a necessary readiness posture,” it said.
Sunday’s fire exchange took place a day after North Korea reported its leader Kim Jong Un’s first public appearance in about 20 days amid intense speculation about his health.
North Korea’s official media published photographs and a report on Saturday that Kim had attended the completion of a fertiliser plant, the first report of his appearance since April 11.
