BRUSSELS (AP) — The European Union is broadening its crackdown on multinationals’ tax avoidance schemes, opening Tuesday an investigation into Amazon’s practices on suspicion the online retailer is not paying its dues on profits made across the 28-nation bloc.

The probe adds another high-profile name to the list of companies targeted by the EU, which is already investigating Apple Inc., coffee chain Starbucks and the financial arm of carmaker Fiat.
