When Indian auto-rickshaw driver Mohammad Javed Khan saw people carrying their coronavirus-stricken parents to hospitals on their backs as they were too poor to afford an ambulance, he knew he had to help. Khan, a 34-year-old driver in the central Indian city of Bhopal, sold his wife's jewellery and converted his three-wheeled vehicle into a small ambulance. His state of Madhya Pradesh, like many other states, has witnessed a spike in cases in recent weeks that had led to shortages of oxygen and other critical medical supplies.
