Linked by a new theory linking the transfer of a large plane carrying high explosives to the deadly attack at the Pearl and Co. airport in Phoenix on Sunday, officials in the United States and Europe are now speculating that the same thing happened to a similar plane on the same day that the bomb went off.
Authorities in Phoenix and New York have been investigating a possible link between the bomb and a large airplane that was on its way from Dubai to Saudi Arabia at the time it exploded.
It was not clear Sunday whether that plane was flying to Saudi or Dubai at the same time as the Pearl Airport bomb.
The two cities said the bomb did not kill anyone and the airport was operating normally.
“We’ve had multiple reports of suspicious items in and around the airport,” Phoenix Mayor Greg Stanton said.
“We’re still working on the source of that.”
New York Mayor Bill de Blasio said the bombs found in the airport were “suspected of being used in the plot.”
“It’s been a real, real difficult week,” de Blasio told reporters Sunday.
“It’s really unfortunate and disturbing.”
In Washington, D.C., a senior law enforcement official said there was a significant overlap in the plots targeting Pearl and the attack at Coors Field.
“It appears that both plots were closely related, but I can’t give any indication that one of them was more successful,” the official said.
The official spoke on condition of anonymity because they were not authorized to discuss the investigation.
