Iran is expelling a German diplomat, the foreign ministry said on Sunday, after Germany reportedly expelled an Iranian diplomat for seeking to obtain nuclear material, AFP reported on Sunday.

Foreign ministry spokesman Mohammad Ali Hosseini said the diplomat was being expelled for activities incompatible with his or her status, but did not reveal the German’s identity.

The weekly Der Spiegel reported last month that Germany expelled an Iranian diplomat posted to Berlin whom it suspected of trying to obtain materiel used in uranium enrichment.
