"Today we received 11 threats, of which two were rejected as fake and nine were acted on," Chilean civil aviation authority DGAC Director Víctor Villalobos said at a press conference.
Two of the flights were operated by Latam Airlines and two by Sky, a budget Chilean airline. Three of the flights have been identified as Latam flight 2369 from Lima to Santiago, Sky Airlines flight 524 and Sky Airlines flight 162, according to the Chilean Directorate General of Civil Aeronautics (DGAC).
The threats were made through an anonymous phone call to the office of the DGAC; Chilean media reported later in the evening that at least 11 false bomb threats to commercial flights had been made.
"The people are being put on other flights and we are going to be open to receive information," Major Diego Rojas, spokesman for the Chilean police, said according to T13.
Sputnik reported the emergency landing of Latam flight 2369 earlier Thursday, noting "Today at 12:48, the Radar Control Center of Peru received a call from its counterparts in Chile, saying they had received a bomb threat concerning Latam Flight LA 2369," Peru's Transportation Ministry said in a statement.
