North Korean news agency says Kim Jong Un makes first public appearance in 40 days

North Korea's official news agency says leader Kim Jong Un has made his first public appearance in 40 days.

KCNA says Kim "gave field guidance" on Tuesday at the newly built Wisong Scientists Residential District. The agency also says that earlier in the day, Kim "visited the newly built Natural Energy Institute of the State Academy of Sciences."

Kim's prolonged absence from public view had fueled speculation about his health and his control over the country.
