Forty state-run Iranian media outlets have jointly offered a new $600,000 bounty for the death of British Indian author Salman Rushdie, according to the state-run Fars News Agency.
Fars News Agency, which is closely affiliated with the Islamic Revolutionary Guards Corps (IRGC), was among the largest contributors, donating one billion Rials - nearly $30,000.
The announcement coincides with the anniversary of the fatwa issued the Ayatollah Ruhollah Khomeini, the founder of the Islamic Republic, the agency said.
Ayatollah Khomeini, the First Supreme Leader of Iran, issued the fatwa against Rushdie on charges of blasphemy for his novel The Satanic Verses on 15 February, 1989.
The Ayatollah called for the death of the book's author along with anyone "involved in its publication".
The new bounty is the largest organised effort to assassinate Rushdie since the fatwa was issued.
