There has been a second dry ice explosion in as many days at Los Angeles' LAX Airport.
The incident occurred at around 8.30pm local time on Monday evening at the airport's Tom Bradley international terminal.
The bomb squad was called to the scene, but no injuries or evacuations were reported, says the Guardian.
Detective Gus Villanueva told ABC News that two other devices were also found at the airport but did not explode.
He added that investigators do not believe the incidents to be related to terrorism.
On Sunday night, a plastic bottle containing dry ice exploded in an employee bathroom in LAX's terminal 2, causing four-hour flight delays as airport police stopped security screening for more than an hour.
Sergeant Karla Ortiz, an airport police spokeswoman, confirmed that there was a dry ice explosion at terminal 2 on Sunday, telling the Daily Mail: "I don't know if this is something that was done accidentally or on purpose. I don't have all the details of why someone would carry dry ice in a bottle."
No arrests have been made in either case.
