The U.S. military is close to identifying the first two American troops from the 55 boxes of human remains from the 1950-53 Korean War that were handed over by North Korea in July, U.S. officials leading the forensic analysis said on Monday.

"The IDs will be made officially in the next couple of days," said John Byrd, the director of scientific analysis at the U.S. Defense POW/MIA Accounting Agency. The families of the dead would be notified first, he said.

President Donald Trump's administration has hailed the handover of the remains as evidence of the success of his summit with North Koran leader Kim Jong Un in June. The White House said on Monday it was looking at scheduling a second meeting.
