Enough protestors had gathered on foot in Los Angeles to shut down the city's 10 freeway.

With cars backed up in their wake, the mob chanted their rallying cry: 'Who's streets? Our street, our freeway.'

Police were unable to clear the roadway and allow traffic to pass until around 7pm and photos show a face-to-face clash between cops and protestors on the highway.

Elsewhere in Los Angeles, protestors have had confrontations with police, according to NBC4 , which reports that LAPD has fired rubber bullets into the crowd.

Bean bag rounds were also used to disperse the Los Angeles crowd and police said D cell batteries and rocks had been thrown at them.

As the night began to wear on in the City of Angels, protests became more serious.

Some protestors climbed atop cars. Some of the cars were even moving, carrying the demonstrators down city streets toward Hollywood, where people would later fill and block the busy Hollywood and Highland Avenue intersection.



Five hundred chanting demonstrators had gathered in one of the the marches through Los Angeles streets by 10pm.

Reverend Jacqueline Lewis addressed Trayvon Martin and gun control as part of her sermon at Middle Collegiate Church.



"We're going to raise our voices against the root causes of this kind of tragedy,' she told the room full of hoodie-clad, emotional congregants. 'We'll aim our fight for justice against the ease with which people can get firearms in this country.'

The New York march made its way to Times Square from Union Square in Manhattan around 6pm.



Leaders yelled calls for justice into bullhorns and hundreds of fists remained raised in the air as neon advertisements backlit the fiery crowd.

As their numbers swelled, the march continued up 5th Avenue toward Manhattan's Harlem neighborhood.

Police threatened to pepper spray unruly demonstrators, whose presence blocked traffic for more than an hour.



As the marchers walked on, they took to 5th Avenue and headed north with the darkened backdrop of Central Park.



As they made their may uptown, tensions seemed to rise.

Some believe the police began to clamp down on the crowd as it approached the Upper East Side home of Mayor Bloomberg.

Arrests had been made by 11pm and at least seven total demonstrators were taken into custody by police on disorderly conduct and related charges.

Earlier that day and one borough over, Solange Knowles, sister of superstar Beyonce, addressed a group at the Brooklyn Borough Hall on Sunday afternoon.



'I really want this to be about Trayvon,' she told gatherers at the demonstration she organized.

Beyonce, 31, took a moment to honor Trayvon Martin during her Mrs Carter Show World Tour concert at Bridgestone Arena in Nashville, Tennessee.



Her concert started about 30 minutes after news of the Zimmerman verdict began to spread.



'I'd like to have a moment of silence for Trayvon,' Beyonce said as the stage grew dark with just a few key lights shining.



Beyonce broke into the chorus of I Will Always Love You, a song written by country music star Dolly Parton and sung by the late Whitney Houston, before transitioning into her hit Halo.

The Knowles sisters are just two of the dozens of celebrities - Rihanna, Nicki Minaj, Kate Walsh and Stevie Johnson among them - who have voiced their opposition to the decision made by the six-woman jury in Florida.



Democratic mayoral hopeful Bill de Blasio took Sunday's demonstrations as an opportunity to address crowds and make his views known.

'The verdict was a slap in the face to justice,' de Blasio announced. 'A young man was killed. Unarmed. It's not an acceptable verdict. The Department of Justice needs to intervene in Florida immediately.'
