US and N Korea upbeat over talks
Envoys from the US and North Korea have expressed optimism after a first day of talks on normalising relations.
US negotiator Christopher Hill said the two sides had reached a degree of understanding on the way forward.
His North Korean counterpart said he expected a fruitful outcome when the talks in Geneva conclude on Sunday.
They follow a deal promising aid and diplomatic benefits if North Korea disables its nuclear programme. It has already shut down a plutonium reactor.
