Title:
Newcastle_upon_Tyne

Context:
From Newcastle International Ferry Terminal, at North Shields, Danish DFDS Seaways run a service to IJmuiden (near Amsterdam). The DFDS ferry service to Gothenburg, Sweden, ceased at the end of October 2006 – the company cited high fuel prices and new competition from low-cost air services as the cause – and their service to Bergen and Stavanger, Norway was terminated late 2008. Since summer 2007, Thomson cruise lines have included Newcastle as a departure port on its Norwegian and Fjords cruise.

Question:
What did DFDS cite as the reasons it terminated operations?

high fuel prices and new competition from low-cost air services
