Joe Biden formally accepts Democratic nomination

The Democratic White House nominee Joe Biden gave an impassioned speech on the fourth and final night of the Democratic National Convention. Mr Biden took aim at President Trump who he said had unleashed "too much anger, too much fear, too much division". Also: German doctors have been allowed to see Alexei Navalny, the Russian opposition activist who's in a coma after a suspected poisoning; and how seaweed could reduce greenhouse gas emissions.
