Demonstrators have taken to streets across the US for a second day to protest at Donald Trump's election victory, voicing worries that Trump would strike a blow against civil rights.
Mr Trump's buildings in New York and Washington were targets of protesters. Police put up security fences around the president-elect's hotel in Washington, not far from the White House, and shielded New York's Trump Tower with a line of fences, concrete blocks and sanitation department trucks.

About 100 protesters marched from the White House - where Mr Trump had his first transition meeting with President Barack Obama - to the newly opened Trump International Hotel, chanting "love Trumps hate."
"This generation deserves better than Donald Trump," said Lily Morton, 17, marching with about 100 classmates from the Georgetown Day School.
"The queer people, coloured people, women, girls, everyone that is going to be affected by this, we need to protest to help them."
After the students marched on, 72-year-old John Allen, of Silver Spring, Maryland, remained behind to protest at the hotel. "We are not going back to this racist white supremacist oligarchy," he said.
Rudy Giuliani, the former New York City mayor and a high-profile Trump supporter, called the demonstrators "a bunch of spoiled cry-babies," in an interview with Fox News.
In San Francisco, more than 1000 students walked out of classes morning and marched through the city's financial district carrying rainbow flags representing the lesbian, gay, bisexual and transgender communities, Mexican flags and signs decrying Trump.
Several hundred students at Texas State University in San Marcos took to the campus to protest Trump's election, with many saying they fear he will infringe the civil rights of minorities and the LGBT community.
White House spokesman Joshua Earnest said Obama supported the demonstrators' right to express themselves peacefully, while Republican National Committee spokesman Sean Spicer urged them to give Trump a chance once he is sworn into office in January.
Organisers used social media to plan and schedule many of the protests. A Facebook group using the name "#NotMyPresident," formed by college and high school students, called for an anti-Trump rally on Inauguration Day, 20 January.
In New York's Washington Square park, several hundred people gathered to protest Trump's election.
More anti-Trump demonstrations are planned heading into the weekend.
