German spying for U.S. alleged
A man was arrested and the American envoy was summoned for a "clarification."
U.S. Ambassador John B. Emerson was called in "in connection with an investigation by the federal prosecutor," the German Foreign Ministry said in a statement. The U.S. envoy "was asked to help in the swift clarification" of the case, it added.
Federal prosecutors say a 31-year-old German man was arrested Wednesday on suspicion of spying for foreign intelligence services. They did not identify the suspect or the intelligence services.
German government spokesman Steffen Seibert told reporters that Chancellor Angela Merkel had been personally informed of the arrest.
The newspapers, which did not identify their sources, said the man was suspected of passing on information about a German parliamentary committee investigating the activities of U.S. and other intelligence agencies in Germany. He claimed to have worked with U.S. intelligence since 2012, they reported.
Seibert said members of the parliamentary panel had also been informed of the arrest.
Reports that the National Security Agency spied on German citizens, including on Merkel's cellphone, have caused friction between Berlin and Washington since they were first published last year, based on documents leaked by former NSA contractor Edward Snowden.
Martina Renner, a member of the opposition Left Party on the parliamentary panel, said the case indicated that anyone who examined Snowden's revelations in detail was subject to scrutiny by U.S. intelligence agencies.
Her panel heard testimony Thursday from two former NSA employees, Thomas Drake and William Binney.
"If the media reports [about the case] are confirmed then there can't just be a legal response, there also has to be a political response," Renner said.
In his testimony, Drake claimed that cooperation between the NSA and Germany's BND greatly increased after the 9/11 terror attacks in the United States. He described the German spy agency as an "appendage" of the NSA.
Seibert said Merkel discussed "foreign policy matters" in a telephone conversation with President Obama late Thursday. He said the conversation focused on Ukraine but wouldn't say whether the arrest was also discussed.
The U.S. National Security Council declined to comment Friday and BND didn't immediately return a call seeking comment.
Roderich Kiesewetter, who sits on parliamentary panel for Merkel's Christian Democrats, said he was "astounded" that the information had been leaked, Bloomberg News reported. "This public spectacle hurts the work of the investigation," he said in a phone interview with the service.
