One of the many consequences of the Russian invasion of Ukraine was the exodus of thousands of foreign students, who were forced to flee the country. Among them were more 18,000 Indian medical students, who made their way to neighbouring European countries in order to be repatriated. But back home, the Indian authorities refused to allow them to continue their studies at medical school. Today, some of these students are returning to Ukraine despite the ongoing conflict and the risks to their safety. Our New Delhi correspondents report.
