U.S. President Donald Trump on Thursday identified the remains of two U.S. soldiers who were killed during the Korean war as Army Master Sgt. Charles H. McDaniel and Army Pfc. William H. Jones.

The return of the remains is part of the agreement Trump signed with North Korean leader Kim Jong Un on June 12 in Singapore.

“Army Master Sgt. Charles H. McDaniel, 32, of Vernon, Indiana, and Army Pfc. William H. Jones, 19, of Nash County, North Carolina, are the first American remains from North Korea to be identified as a result of my Summit with Chairman Kim,” Trump said via social media.
