Thiruvananthapuram: A message warning of a potential drone attack at Thiruvananthapuram International Airport was received on Saturday via email. In response to the threat, airport authorities have issued a security alert. The message arrived at the airport's email inbox around noon today, prompting heightened security measures.

The airport authorities have ramped up surveillance and imposed stricter security protocols around the airport perimeter. This is not the first time that bomb threats have been received via email targeting flights at the airport, though previous such threats were later determined to be hoaxes. However, the message concerning a possible drone attack is being taken seriously by the authorities.

Last year, a series of hoax threats were made to flights across the country, leading to the arrests and punishments of the individuals involved. 

Further details regarding the Thiruvananthapuram airport incident are awaited, as authorities are yet to provide more information.
