Security forces in Natanz have arrested two suspected "spy pigeons" near Iran's controversial uranium enrichment facility, the reformist Etemad Melli newspaper reported on Monday.
One of the pigeons was caught near a rose water production plant in the city of Kashan in Isfahan province, the report cited an unnamed informed source as saying, adding that some metal rings and invisible strings were attached to the bird.
This World War I vintage (1918) picture came off the Signal Corps wall around 1945 when Art Block was given the picture. It depicts cameras attached to birds before flying over enemy lines.
"Early this month, a black pigeon was caught bearing a blue-coated metal ring, with invisible strings," the source was quoted as saying of the second pigeon.
The source gave no further description of the pigeons, neither their current status nor what their fate will be.
Natanz is home to Iran's heavily-bunkered underground uranium enrichment plant, which is not far from Kashan.
