President-elect Donald Trump has taken to Twitter to complain about continuing protests around the US over his victory, calling it "unfair".

Scattered protests around the country continue to follow the unexpected election of Mr Trump as president, with hundreds marching in Dallas, Madison, Oakland, Philadelphia, Baltimore and Grand Rapids, Michigan.

The protests first started on election night but continued on Wednesday when thousands took to the streets across the country, burning effigies and bringing a highway in Los Angeles to a standstill.

Los Angeles Mayor Eric Garcetti condemned anti-Trump demonstrators who damaged property and blocked traffic.


But he also said Thursday he's proud of the thousands of people who took to streets peacefully on Wednesday.

Thursday night's protests have been smaller but Mr Trump took to Twitter to express his concerns, hours after meeting US President Barack Obama at the White House for a tour of his new home.

"Just had a very open and successful presidential election. Now professional protesters, incited by the media, are protesting. Very unfair!" he tweeted.

Trump supporters have also taken to social media to express their scorn of the protests, saying demonstrators are hypocrites for not accepting the democratic process because they don't like the results.

The third night of protests have drawn thousands of people.

Thousands took to the streets in Madison, Wisconsin, marching through Library Mall from UW-Madison's Bascom Hall to the State Capitol.

In Baltimore a crowd of about 600 people marched through Baltimore to the stadium where the Ravens were playing a football game.

The protest brought traffic to a standstill but was otherwise peaceful, two people were detained but have not been charged.

About 300 people gathered in downtown Dallas to demonstrate against Mr Trump's election.

Protesters carrying signs bearing such slogans as "Love Trumps Hate" and "Spirit Unbreakable."

A crowd that included parents with children in strollers gathered Thursday night near Philadelphia's City Hall. They held signs bearing slogans like "Not Our President," "Trans Against Trump" and "Make America Safe For All."

About 500 people turned out in Louisville, Kentucky, chanting and carrying signs as they marched downtown. A day earlier, five people were arrested at Western Kentucky University as demonstrators protested Trump's election.

Meanwhile more than 1000 high school students in San Francisco chanted "not my president" and waved rainbow and Mexican flags as they marched through the city's downtown on Thursday.
