Washington (CNN) — Two Amazon Prime Air delivery drones struck a crane in Arizona, resulting in “substantial” damage and a fire Wednesday, prompting the company to ultimately suspend delivery drone operations.

The two MK30 drones crashed into the boom of a crane in Tolleson, Arizona, near Phoenix, Wednesday around 10 a.m., according to the Federal Aviation Administration. No injuries were reported.

Helicopter video from CNN affiliates KTVK/KPHO shows the remains of the more than 80 pound drones shattered on the ground.

According to Amazon, the suspension of drone operations is temporary and was a decision made by the company.

Terrence Clark, an Amazon spokesperson, confirmed they are working with the relevant authorities to investigate the incident.
