ADVERTISEMENTUS President Joe Biden and his wife Jill paid their respects to the victims of the US' latest mass shooting in Buffalo, New York State.
Their first stop was at a makeshift memorial outside the supermarket where the attack took place.
A gunman opened fire on Saturday killing 10 people in what is believed to have been a racially motivated hate crime.
In a speech at a nearby community centre, Biden called for stricter gun laws and urged Americans to reject racism and embrace the nation's diversity.
"Jill and I bring you this message from deep in our nation's soul," Biden said. "In America, evil will not win, I promise you. Hate will not prevail, and white supremacy will not have the last word."
The president went on to say that the 18-year-old suspect, who had identified himself as a fascist and white nationalist in a document posted online, belonged to "a hateful minority".
