According to the source, the delivery strategy involves six Greek C-130 cargo planes, ten Canadian planes, and five New Zealand planes.

The news outlet also accused Greek officials of withholding information on arms transfers to Kiev.

On February 27, Athens sent 40 tonnes of "defense equipment" to Ukraine via the border of Poland. Since then, the Greek government has indicated repeatedly that it will no longer supply additional weapons to Kiev in order not to jeopardize its own defense capabilities.

The reports of further shipments of Greek heavy weaponry to Kiev have sparked outrage from the opposition, which accuses Athens of endangering national security and concealing agreement specifics from the public.
