Travel agent Anna Koval, who transformed her office into the headquarters of a volunteer operation helping participants of protests against presidential election results, works in Minsk, Belarus August 18, 2020. Koval's group of around 10 people, many of them doctors able to provide first aid, coordinated on social media as best they could amid an internet blackout to tip each other off about the location of protesters in need and the risks on the ground.
