Two civilians were found dead Wednesday on Yeonpyeong Island, bringing the death toll from the North Korean artillery attack a day earlier to four, including two marines. Scores of other soldiers were also wounded in the barrage, and homes and facilities damaged.

They are the first civilian deaths by shellfire by the North since the end of the Korean War.

The Incheon Coast Guard said they found two bodies around 3:20 p.m. Wednesday at a construction site on a Marine Corps base on the island.

The deceased were identified as Kim Chi-baek, 61, and Bae Bok-chul, 60, both of whom were construction workers hired to build a residential building at the base.

The Marine Corps had reported to police that the two went missing when they evacuated 10 other employees from the site because of the attack.
