Amazon said on September 13 that it has suspended operational cooperation with 21 Air, the operator of Flight 7598, after what it called a tragic incident over the weekend, according to Jiemian News. Amazon spokesperson Kelly Nantel said the company will continue to support the investigation.

Separately, CCTV News reported that at about 2 p.m. local time on September 6, an Amazon cargo plane, a Boeing 767-300 flying from Puerto Rico, veered off the runway while landing at Miami International Airport, triggering a large emergency response and forcing the airport to suspend operations. Miami-Dade County police and fire officials said the accident had left at least five people dead and five injured.
