The delegations of North Korea and US held a 90-minute bilateral meeting on Thursday, but failed to narrow their differences, said an official of the South Korean delegation to the six-party talks.

"North Korean and US delegation chiefs didn't narrow their differences in the one-on-one meeting" which started at about 11:40 AM, said the South Korean official on condition of anonymity.

This is the second bilateral meeting between the two delegations since the fourth-round six-party talks resumed Tuesday, involving China, North Korea, US, South Korea, Russia and Japan, after a five-week recess.
