From a Korean-language article in Chosun Ilbo
Approx 2 pm this afternoon,
NK fired three (artillery) rounds near Yeonpyeong Island which was attacked last year.
One landed on NLL(the sea dividing line.)
SK responded by firing back three rounds of its own.
All SK fishing boats returned to the shore and residents were evacuated to shelters.
So far no casualties were reported and NK appeared to fire at an uninhabited island called Yong-mae-do.
