An Indian Air Force (IAF) aircraft from Poland’s Rzeszow carrying students evacuated from northeastern Ukrainian city Sumy landed at the Hindon air base on Friday afternoon. This is the second of the three flights being operated by India on Friday -- one each by Air India, IndiGo and the IAF -- from Rzezow to Delhi to bring back 600 students who have recently been evacuated from Sumy.

External Affairs Minister S Jaishankar, in a post on Twitter, specifically mentioned that the evacuation of Indian students from the northeastern city of Sumy was "particularly challenging".
