Thiruvananthapuram International Airport on Sunday received a bomb threat via email.
The bomb squads are conducting thorough checks across the terminals.
Further investigations are underway.
On Saturday, various hotels in Kerala capital received bomb threats through email.
Following threats, bomb disposal units and dog squads were deployed to carry out searches.
An officer of Cantonment police station said that inspections were carried out at all the hotels where the bomb threats were received, but nothing was found.
Therefore, the threats were a hoax, the officer added.
The police were looking into the origins of the threatening email which claimed that IED explosions will take place at various hotels in the state capital, including the Hilton Hotel in the heart of Thiruvananthapuram city.
In the last couple of months, bomb threats by email were received at district collectorates and offices of Revenue Divisional Officers across the state and also, most recently, at the Kerala High Court.
All of these threats had been ruled out by the police as hoaxes after carrying out extensive inspections.
In January this year, Telangana's Rajiv Gandhi International Airport (RGIA) had also received a bomb threat call which prompted the airport authorities to conduct thorough searches with the bomb squad.
The call was made by a person, identified as Nitin, from the Kamareddy district. He reportedly made approximately 100 calls to the airport, as per police officials.
"A person named Nitin had made 100 calls to the airport and claimed that there was a bomb at the airport. He is a narrative of Rajampeta police station limits of Kamareddy and his parents say that he is mentally disturbed." RGIA police station Inspector had said.
