Iran has expanded the tunnels it uses to hide a major part of its nuclear weapons program to a network covering a large area of southeastern Tehran, an Iranian exile who opposes that nation's Islamic government said.
Alireza Jafarzadeh said the secret construction of missiles extends well beyond Parchin, a military zone 20 miles (30 kilometers) southeast of the Iranian capital. Jafarzadeh told reporters in September about the Parchin tunnels.
On Monday, Jafarzadeh said that on orders of Ayatollah Ali Khamenei, the Iranian defense ministry has taken over an area in eastern and southern regions of Tehran.
Jafarzadeh is credited with having aired Iranian military secrets in the past, but US officials consider some of his assertions to have been inaccurate.
