Ferguson: Police arrested 15 people in the protest-hit St Louis suburb of Ferguson on Friday in more demonstrations demanding justice for an unarmed black teenager killed by police.
Tensions escalated late Friday during an initially calm demonstration after police said protesters were illegally blocking an avenue.
The demonstration in Ferguson came after protesters earlier in the day temporarily shut down three large malls in suburban St. Louis.
There have also been sporadic demonstrations around the United States after a Missouri grand jury decided earlier this week not to indict the white policeman who shot dead 18-year-old Michael Brown in August.
Monday's announcement that officer Darren Wilson will not face charges sparked protests, looting and eruptions of gun fire in Ferguson, and demonstrators were again on the streets in the predominantly black suburb on Friday.
