Aviation security agencies were on high alert on Wednesday after a series of bomb threat messages were reported — one targeting an Air India Express flight from Mumbai to Varanasi, and another claiming that five major airports, including Delhi and Mumbai, were under threat, reported the PTI.

According to official sources, IndiGo Airlines received a message warning of potential bomb attacks within 24 hours at Delhi, Mumbai, Hyderabad, Chennai, and Thiruvananthapuram airports. The Bomb Threat Assessment Committee (BTAC) convened at the Delhi Airport soon after the message was received. Following detailed verification, the threat was declared “non-specific”, officials told the PTI.
