Authorities in Iran nabbed two birds believed to be “spy pigeons” near the country’s contentious nuclear facility, the Agence France-Presse reported Monday.

Both pigeons were caught near the city of Natanz, which is home to Iran’s uranium enrichment plant, AFP reported. Both had metal rings and invisible strings attached to them.

A source declined to mention what will happen to the pigeons now that they’ve been caught.

The results of a six-year probe released last month did not rule out the possibility that Iran may be running clandestine nuclear programs, a chief U.N. nuclear inspector said told the Associated Press.
