Officials at Los Angeles International Airport have found four bottles containing dry ice since Sunday, two of which burst. The plastic bottles were found in restricted areas of the airport, accessible only to authorized personnel.

Police do not believe that the incidents are connected to terrorism, according to the Associated Press.

One explosion Monday night did not affect any flights at the airport, but the previous explosion Sunday temporarily halted operations at the airport’s Terminal 2, the Los Angeles Times reported. Four flights were delayed.

No arrests have been made in connection with the dry ice.
