ROME: Italian regulators hit Amazon with a massive 1.1-billion-euro ($1.3-billion) antitrust fine Thursday for allegedly abusing its dominance to push its logistics business, in the latest European action against US Big Tech.

The e-commerce firm, one of several technology giants in the firing line over their business practices, was swift to condemn what it called a “disproportionate” sanction and said it would appeal. Italy’s competition watchdog said Amazon abused its dominant position by promoting its own logistics or fulfilment service — which ships and delivers packages — on its Italian platform to the detriment of third-party sellers who did not use it.
