Thousands of demonstrators have taken to the streets of several US cities to protest against the election of Donald Trump, the reports.

Many shouted the slogan “Not my president”. Others burned orange-haired effigies of the businessman.

Mr Trump will become the 45th US president after securing a surprise victory over Hillary Clinton.

He is due to meet current White House incumbent Barack Obama for talks aimed at ensuring a smooth transition.

Mr Obama – who had branded Mr Trump “unfit” for office and campaigned against him – urged all Americans to accept the result of Tuesday’s election.

“We are now all rooting for his success in uniting and leading the country,” he said.

Defeated Mrs Clinton also told supporters Mr Trump had to be given a “chance to lead”.

Despite their calls, protesters gathered in several cities across the country.

• In New York, thousands marched on Trump Tower, attacking Mr Trump’s policies on immigration, gay rights and reproductive rights. Fifteen people were arrested, the New York Times reported.
• Protests were largely peaceful but in Oakland, California, some demonstrators smashed shop windows and threw missiles at riot police, who reportedly responded with tear gas
• A mass anti-Trump rally shut down a key freeway in Los Angeles
• In Chicago, crowds blocked the entrance to Trump Tower, chanting: “No Trump, No KKK, No Fascists USA”
• In Portland, Oregon, demonstrators temporarily closed an interstate highway

Demonstrations also took place in Philadelphia, Boston, Seattle and San Francisco, among other cities.
