Following almost a week of relentless Russian attacks on Kyiv and non-stop air raid alerts, Ukrainian President Volodymyr Zelenskyy issued a stark warning to international airlines and insurers: "Russian airspace will effectively be closing."
In his evening address on 1 September, Zelenskyy said the consequences of the war Moscow launched more than four years ago could no longer be confined to Ukrainian territory and that Kyiv's ever-growing drone operations would soon render Russian airspace unsafe.
