Former US president Jimmy Carter says the Zionist regime possesses 150 nuclear warheads in its arsenal, according to The Times of London.

Since his presidency, Carter has over the years become known as a fierce critic of Israel's policies.

The southern town of Dimona is home to a reactor that is the centerpiece of Israel's illegal nuclear weapons program. The regime began developing a nuclear reactor in Dimona in the 1950s.

The Zionist regime is reportedly the only nuclear-armed country in the Middle East which has refused to sign the Non-Proliferation Treaty.
