Throngs of demonstrators have held marches across the United States to protest Republican Donald Trump's surprise victory in the US presidential election.

They blasted his campaign rhetoric about immigrants, Muslims and other groups.

In New York, thousands of protesters filled streets in midtown Manhattan as they made their way to Trump Tower, while hundreds of others gathered at a Manhattan park and shouted: "Not my president."

A demonstration of about 6,000 people blocked traffic in Oakland, California, police said.

Protesters threw objects at police in riot gear, burned trash in the middle of an intersection, set off fireworks and smashed store front windows.

Police responded by throwing chemical irritants at the protesters, according to a witness.

In downtown Chicago, 1,800 gathered outside the Trump International Hotel and Tower while chanting phrases like: "No Trump! No KKK! No racist USA!"
