The US is not happy about Germany going international with its hunt for the CIA agents responsible for kidnapping Khaled el-Masri. American diplomats vented their anger in meetings with German government officials.

The case of Khaled el-Masri has managed to drive a wedge between Washington and Berlin. The German investigation into what exactly happened to the German citizen Khaled el-Masri, and who was responsible, is becoming an increasingly prickly thorn in the side of Germany-US relations. Indeed, after a Munich court issued arrest warrants against 13 CIA agents at the end of January for complicity in his kidnapping and subsequent torture, high-ranking US diplomats sought to convince the German government not to expand the search for the perpetrators internationally, German government sources have told DER SPIEGEL.

Following the Jan. 31, 2007 issuing of the arrest warrants, US diplomats spoke with foreign policy advisors of German Chancellor Angela Merkel to express Washington's displeasure that the case was being forwarded to Interpol, the international police organization that facilitates policing cooperation among 186 member countries -- including the US and Germany.
