NEW DELHI: The closure of Iranian airspace after Israel attacked its nuclear sites has led to multiple international flights either diverting or discontinuing their journey & returning to origin. With Pakistan airspace already closed for Indian carriers, and vice versa, & not all airlines overflying Afghanistan, the situation in Iran is likely to make flights between north India and the west even longer, even making fuelling stops must in some cases.In a statement, Air India said: “Due to the emerging situation in Iran, the subsequent closure of its airspace and in view of the safety of our passengers, the following Air India flights are either being diverted or returning to their origin.
