Nobel Prize-winning anti-nuclear campaign group International Campaign to Abolish Nuclear Weapons (ICAN) has offered to pay for the cost of the historic summit between North Korean leader Kim Jong Un and U.S. President Donald Trump, including the hotel bill for the impoverished state's leader stay in Singapore.

The offer comes after a media report said that the cash-strapped North may have trouble bearing the cost of its leader's stay and the large delegation of security and support staff for the meeting scheduled for June 12.

ICAN, which won last year's Nobel Peace Prize, said it is willing to use its prize money to pay for any accommodation or meeting space needed to make the summit a success.
