- Donald Trump's presidency has put a spotlight on the risks of nuclear weapons, the Nobel Peace Prize winning nuclear disarmament group ICAN said on Friday.

"The election of President Donald Trump has made a lot of people feel very uncomfortable with the fact that he alone can authorise the use of nuclear weapons," the head of the International Coalition to Abolish Nuclear Weapons, Beatrice Fihn, told reporters in Geneva.

She said the US leader appeared to have a track record of "not listening to expertise", and insisted his supervision of a massive nuclear arsenal "just puts a spotlight" on the dangers of such weapons.
