Tehran (Xinhua) -- The French-Italian aircraft manufacturer ATR delivered five more turboprops to Iran on Sunday, official IRNA news agency reported.

The ATR 72-600 passenger planes landed at Tehran's international Mehrabad airport on Sunday morning, a day before the return of first round of US sanctions against Iran.

Flight licenses have been issued for the ATR passenger planes to join Iran Air's fleet, the Iran Air announcement said.

In April 2017, Iran Air signed a contract with ATR to purchase 20 short-haul passenger jets worth 576 million US dollars. Iran had already received eight ATR 72-600 aircraft and deployed them in domestic flights.

After US President Donald Trump's withdrawal from the Iranian nuclear agreement, also known as the Joint Comprehensive Plan of Action (JCPOA), in May, Washington is trying to bring sanctions back on Iran with the aim of blocking Iran's international financial transaction and reducing its oil exports to zero.

Under the JCPOA, Iran put limits on its nuclear program in exchange for the removal of nuclear-related sanctions imposed on Tehran.
