Protesters take to street in San Francisco against U.S. president-elect

Two groups of protesters took to the street in San Francisco on Wednesday night against Donald Trump, who was elected a day earlier to be the next U.S. president.

The first group, of about 60 young people, gathered in front of City Hall while about a dozen police officers lined up on the steps leading to the historic building housing the San Francisco county and city government.

While at least two girls talked about being "scared" by what Trump said during the campaign about women and about ethnic minorities, allegedly with sexist and racist tones, a dozen protesters took turns speaking against the president-elect.

Less than half an hour after the first group left the scene, hundreds of young people of various ethnicities walked along a main street and converged at the same location.

Organized by a coalition known as ANSWER, they chanted in unison to the beat of drums for racial equality and women's rights and against the discrimination they said was emboldened by Trump's rhetoric along the campaign trail.

ANSWER, for Act Now to Stop War and End Racism, called for "emergency protests" on Wednesday in six U.S. cities, including at Trump International Hotel & Tower in Chicago, and other locations in New York and Los Angeles, in response to the "shock result" of the presidential race.

A speaker of the coalition said it was the first step against the president-elect's "bigoted, extreme right wing agenda" and more would follow in the coming days.

Both protests in the northern Californian city ended without incidents. However, in the neighboring San Francisco Bay city of Oakland tear gas was deployed by police as protests entered into the second night. The crowd reportedly grew to some 7,000 people at one point on Wednesday and several buildings were vandalized; bonfires were set on at least one street.

Students at several schools in the cities of Oakland, Berkeley and San Jose, and in Contra Costa County earlier in the day walked out of class along with their teachers. At Berkeley High School, 1,500 students walked to downtown Berkeley in the morning and staged a silent sit-in at a plaza.

In Los Angeles, protesters blocked a section of Highway 101 for hours on Wednesday night.

A majority of voters in California, the largest state in the country, voted for Democratic candidate Hillary Clinton rather than her Republican counterpart Trump.

Up north in the state of Oregon, about 300 people marched through downtown Portland and dozens of them blocked traffic in the city and enforced a delay for trains on two light-rail lines. A crowd of much smaller size showed up in downtown Seattle in the state of Washington, and four males and one female were injured in an unrelated shooting incident nearby.

Throughout the country, protesters were mainly young adults, and statistics show 55 percent of people in the group aged 18 through 29 voted on Tuesday for Clinton, and 37 percent of those in the same group voted for Trump. Endi
