Minister defends preparedness against novel threat after officials detonate device suspected to be from Ukraine

Authorities in Greece have intensified investigations into how an explosive-packed drone ended up in waters off the west of the country.

An inquiry, involving specialised military teams, broadened at the weekend after bomb disposal experts detonated the unmanned device at sea.

The Greek defence minister, Nikos Dendias, said the drone, suspected to be of Ukrainian origin, almost certainly came from “a foreign state” although he stopped short of identifying the country.

“We know what it is, and we more or less know what it contains,” he said, while also attempting to allay fears that Greece lacked the military capabilities to defend itself against such emerging technology. “We have nothing to envy, we are creating the possibilities so that our homeland can equip its combat navy with the most developed drones and anti-drone systems that currently exist.”
