Washington (CNN) Iran tried to acquire technology that could be used for a military nuclear program, calling into question whether it is living up to an international agreement intended to curb such an effort, according to Germany's domestic intelligence service.

The intelligence report from the German Federal Office for the Protection of the Constitution found that despite the deal Iran has continued its "illegal proliferation-sensitive procurement activities" at a "quantitatively high level."

"This holds true in particular with regard to items which can be used in the field of nuclear technology," the report added.

But the State Department said it has no indication Iran is violating the deal.

"We have no information to indicate that Iran has procured any materials in violation" of the Joint Comprehensive Plan of Action, as the Iran agreement is formally known, said State Department spokesman John Kirby, who added that the German report covers 2015 and makes no distinction between the periods before and after the nuke deal.
