A former chief of Israel's Mossad spy agency has rejected claims made by Israeli Prime Minister Benjamin Netanyahu in his address to Congress about Iran's nuclear program.

In an interview aired on Channel 2 TV Friday, Meir Dagan questioned Netanyahu's claim that the emerging deal would allow Iran to create a bomb within a year or less.

"Bullshit," Dagan said. "The time is longer than what he describes."

Dagan also rejected Netanyahu's assertion that Iran's intercontinental ballistic missile program could allow it to deliver a nuclear arsenal to the U.S. Dagan said, "The missiles cannot reach the U.S."

Dagan is a fierce critic of Netanyahu's approach to Iran.

Dagan directed the Mossad from 2002 to 2010, a period when it reportedly carried out covert attacks against Iran's nuclear program.
