A top IOC official says a proposal for the Japanese cities of Hiroshima and Nagasaki to co-host the Olympic Games in 2020 as a way of promoting world peace is unlikely to happen.
The two cities were the site of atomic bombings at the end of the second world war.
Executive director Gilbert Felli says the Olympic charter clearly states only one city can host the games.
He says there are proposals to review bid policies, but these are unlikely to be in force before the bid process for the 2020 games start in 2 years time.
The 2 cities are only separate islands almost 300km apart.
