incursion

The announcement came just one day after the second anniversary of a coordinated attack on Israel by Hamas militants, an incursion that kick-started the current wider war in Gaza.

The "airspace violations" come at a time of heightened tension in Europe after a number of drone incursions, suspected of being linked to Russia, caused air traffic disruption.

German Chancellor Friedrich Merz said ahead of the summit that airspace incursions were getting worse and that it was "reasonable to assume the drones are coming from Russia".

The separate question of whether the tanker was used to launch last week's drone incursion into Danish airspace remains unresolved.

EU leaders have been meeting in Copenhagen under pressure to boost European defence after a series of Russian incursions into EU airspace, and days after the drones targeted Danish airports.
