German rail operator Deutsche Bahn and Deutsche Telekom are ending projects in Iran after the United States imposed new sanctions against Tehran. Washington has also warned that firms doing business with Iran would be barred from doing business with the US. New US sanctions against Iran took effect last week and several European companies have suspended plans to invest in the country, including oil major Total as well as carmakers PSA, Renault and Daimler. State-owned Deutsche Bahn is involved in two projects in Iran via its subsidiary, a spokeswoman said on Thursday. “Both projects will be ended in August and September 2018 respectively,” she said. Detecon, a subsidiary of T-Systems – Deutsche Telekom’s IT services arm – has terminated its business in Iran, a spokesman said. Detecon offers consulting services to companies in the telecommunications industry.
