USA: Police repeatedly charge protesters as Portland chaos continues

Violence continued in Portland, Sunday morning, as protesters rallied for the fifth night in a row against President-elect Donald Trump. Police officers fired round of teargas and pepper balls, before repeatedly charging protesters. Some 19 demonstrators are thought to have been arrested over the course of Saturday night and Sunday morning.
According to local police, the protest devolved into a riot with protesters reportedly throwing objects at police, vandalising property and blocking streets.
After Trump's win was announced earlier this week, there have been multiple large demonstrations against the president-elect in several large US cities, including in Chicago, Los Angeles, Washington DC and Seattle. Most the demonstrations have been peaceful, with several, namely in Portland, descending into sporadic violence.
Trump declared victory in the early hours of Wednesday morning, after his Democrat rival Hillary Clinton called him to concede defeat following a bitterly fought election battle. Trump beat Clinton in a surprise landslide victory, garnering 278 of the Electoral College votes, while the Democratic candidate received 218.
