The United States has stopped the sale of four major armed drones to Ukraine due to security concerns.
According to Reuters news agency, the US Department of Defense raised objections to the sale of drones and expressed concern that they could fall into the hands of the enemies.
The White House has approved the decision to sell armed drones 'gray eagles' to Ukraine.
According to the Defense Department, if Russia has access to radar and surveillance equipment installed in drones, it could pose a threat to US security.
Earlier, these concerns were neglected, but they were raised at meetings in the Defense Department last week, after which their sales to Ukraine have been stopped.
Defense Department spokesman Soo Goff says that US defense equipment is a normal process to evaluate the security of technology before transfer to other countries, and all cases are decided on merit basis.
Top Defense Department officials are reviewing the agreement with Ukraine, after which a decision will be made.
Half -missiles can also be installed in drones equipped with advanced technology that can use against Russia during the Ukraine War.
According to US military budget documents, a drone costs $ 10 million.
Ukraine has repeatedly demanded a shipment of heavy weapons from Western countries and has also criticized some European leaders for failing to supply weapons.
North Atlantic Treaty Organization (NATO) Secretary General Stoltenberg addressed a press conference after a key summit on Tuesday that Western countries should send more heavy weapons to Ukraine to counter Russia.
