Nancy Allen and Brian Allen stand outside their home as high winds push smoke and ash from the Currowan Fire towards Nowra, New South Wales, Australia, January 4, 2020. Reuters photographer Tracey Nearmy: "Covering Australia's sparsely populated regions is difficult. And when the bushfires started this summer, getting there was tricky. After a day of travelling, I found myself in smoky red haze face-to-face with Nancy Allen in Nowra, New South Wales. Nancy and her husband Brian, dressed in a singlet and shorts, were trying to defend their home with a garden hose. The fire bearing down on their town was so intense, it was creating its own pyrocumulonimbus storm, and the police had evacuated the area hours earlier. Yet, Nancy and Brian stayed in the swirling smoke and ash, anxiously wetting down the front of their house. Mistaking me for an emergency crew, Nancy rushed over to ask me what they should do. Given that the suburb had already been evacuated, I told them to follow the advice to go to the closest evacuation centre. Their home was close to dense bushland, so it was worrying to see them still on their property an hour later. Nancy's expression in this photograph summed up the shock and disbelief many Australians felt at the ferocity and enormity of these fires."

Protester Patrick Hutchinson carries a suspected far-right counter-protester who was injured, to safety, near Waterloo station during a Black Lives Matter protest following the death of George Floyd in Minneapolis police custody, in London, Britain, June 13, 2020. Reuters photographer Dylan Martinez: "The crowd parted right in front of me. I was in the right place at the right time, and incredibly lucky from that point of view. A Black protester emerged from the melee, walking briskly towards me, carrying a white man with injuries to his face in a fireman's lift over his shoulder. The anti-racism protests in London that Saturday had been fluid and unpredictable. After witnessing sporadic, minor clashes between demonstrators and police in Trafalgar Square, I switched attention to nearby Waterloo Bridge, where several hundred anti-racism protesters had gathered. They took over the whole of the bridge. There was a traffic jam going from south to north, but the vibe was good – cars were honking and people were celebrating. The mood quickly turned ugly when they encountered a group of counter-protesters and clashes broke out. I saw a skirmish and someone falling to the ground before the two men appeared through the crowd. Some people shouted out that the assault victim was a member of the far-right. Reuters journalists at the scene said he had been beaten in a skirmish with anti-racism protesters. This picture went viral on social media and was featured in news bulletins. Patrick Hutchinson has been hailed a hero for carrying the injured man to safety during the scuffle. 'It was the right thing to do,' he told Reuters later. 'We didn't want the narrative changed and the focus taken away from what we are all fighting for, and that's true equality.'"
