Volodymyr Zelenskyy has accused Moscow of an “obvious expansion of the war” and called on allies to issue sanctions after a Russian drone entered Romanian airspace and hovered near the Ukrainian-Polish border on Saturday. Romania’s defence ministry said on Saturday its airspace had been breached by a drone during a Russian attack on infrastructure in neighbouring Ukraine. Romania scrambled two F-16 fighter jets late on Saturday to monitor the situation after the strikes, the ministry said in statement.

Polish authorities said its aircraft and those of Nato allies were deployed in a “preventive” operation in Poland’s airspace because of drone strikes in neighbouring areas of Ukraine. The airport in the eastern Polish city of Lublin was closed and the alert lasted around two hours. Russian drones also entered Polish airspace on Wednesday, which Poland shot down. US secretary of state Marco Rubio called the Russian incursion into Poland “an unacceptable and unfortunate and dangerous development” but questioned whether Poland had been deliberately targeted.
