Iran reportedly reached an agreement Sunday to buy 100 planes from Boeing, pending the final authorization from U.S. Treasury officials.

Reuters, citing an Iranian official’s remarks published by a state-run newspaper, reported that 230 of the country’s 250 passenger planes have to be replaced.

Ali Abedzadeh told the daily Iran that a deal had been signed with Boeing to buy 100 aircraft.

According to Reuters, Boeing has only been allowed to present products to Iranair and several other airlines as it tries to catch up with Europe’s Airbus.

Top House Republicans have raised some concerns that could eventually kill the deal between Iran and Boeing, warning it could end up benefiting Iran’s military and the terror groups Hamas and Hezbollah.

While the talks have not drawn objections from the Obama administration, Reps. Peter Roskam, R-Ill., and Jeb Hensarling, R-Texas, sent a letter Thursday raising concerns about Tehran's history of using commercial planes to support "hostile actors."

“We strongly oppose the potential sale of military-fungible products to terrorism’s central supplier. American companies should not be complicit in weaponizing the Iranian Regime,” the lawmakers wrote in the letter to Boeing CEO Dennis Muilenburg.

Though the Iranian official didn’t disclose Sunday the terms of the deal, a source told The Washington Post that the deal could be worth more than $17 billion.

If agreed, the deal would be one of the most significant since the easing of trade sanctions on the country in January as part of the Iran nuclear deal signed last year.
