SEOUL, Sept. 28 (CGTN) - The Republic of Korea (ROK) and the United States will discuss the recent killing of an ROK official by Democratic People's Republic of Korea (DPRK) soldiers, Yonhap News Agency reported on Monday.

The ROK's top nuclear envoy, Lee Do-hoon, will reportedly soon hold talks with U.S. Deputy Secretary of State Stephen Biegun over the incident as well as discuss the possibility of resuming humanitarian assistance to the DPRK.

A ROK fishery official is reported to have been killed and burnt by DPRK soldiers near the sea border.

In a rare move, the DPRK's leader Kim Jong Un issued an apology for the official's death in DPRK waters.

Kim sent a letter to ROK President Moon Jae-in saying he feels "very sorry" and the incident should not have happened, an official told a briefing on Friday.

Meanwhile, the DPRK said it launched its own operation to search for the body, but warned the ROK's naval operations in the area could escalate tensions, the KCNA state news agency reported.

"We also took more necessary security measures in order to make sure that no more incidents spoiling the relations of trust and respect between the north and the south would happen in any case, true to the intention of our Supreme Leadership," a KCNA report said on Sunday.
