PHILADELPHIA (AFP): As poll workers scrambled Thursday to tally ballots in the key US state of Pennsylvania, supporters of President Donald Trump and his Democratic rival Joe Biden held tense demonstrations at the main vote counting centre in Pennsylvania, the state's largest city.

Biden supporters want every vote counted, while Trump backers want votes that came in by mail after Election Day to be ignored – and support the president's unsubstantiated claims that the mail-in ballot system was riddled with fraud.
