48 tourists from the north-eastern state of Tripura, who were stuck in the west Uttar Pradesh city of Agra for over a month because of the lockdown over the coronavirus pandemic, have finally started their journey back home this afternoon, in a semi-luxury bus. But the journey back will be very tough - it will take at least three days of non-stop driving as the distance between Agra and Tripura's capital Agartala is a massive 2,224 kilometres and the bus will pass through UP, Bihar, Bengal, Assam and Meghalaya before entering Tripura.
