The Azerbaijani military is reported to have purchased U.S.-made Bell-412 helicopters which will be showcased at the country’s military parade in Baku on 26 June.

It is unclear how the Bell-412 copters produced by American aircraft manufacturer Bell Helicopter reached Baku given the U.S. legislation banning the country to supply arms to a party to conflict, political scientist Suren Sargsyan said in a Facebook post.

He calls on the Armenian states structures and U.S.-based organizations to take urgent efforts towards identifying who is behind the copters sales to Azerbaijan.

“The Armenian Foreign and Defense Ministeries, as well as the U.S.-based organizations should immediately take action to figure out who has sold or resold the helicopters to Baku,” Sargsyan stressed.

The armed forces of Turkey, Saudi Arabia, Pakistan and a number of other countries operate Bell-412 helicopters, the expert added.
