An unidentified drone was spotted near a naval station in Chennai around 9:15 pm on Monday. Sources said the drone was airborne for around 5-10 minutes.

Security forces have increased vigilance on territorial waters and surrounding borders in the wake of heightened tension between India and Pakistan.

Considering events that have transpired over the last couple of days, there are chances that drones or other unidentified flying objects (UFO) could infiltrate Indian airspace.

On Monday, Indian Air Force shot down an unidentified flying object UFO, later identified as a drone, after it was detected over the Indo-Pak International Border in Rajasthan.

Top defence sources said the unidentified aircraft was most likely to be a drone, which had entered Indian airspace in the morning.

Indian Air Force scrambled Sukhoi-30MKI fighter jets that shot down the drone, parts of which were discovered later near Fort Abbas in Pakistan's Punjab Province.

Tension between the two countries escalated after Pakistan-based terror group Jaish-e-Mohammed carried out a suicide bombing attack, killing at least 40 Central Reserve Police Force paramilitary troopers.

India launched a subsequent non-military airstrike on multiple terror camps across the Line of Control (LoC) in Pakistan.

Pakistan Air Force (PAF), in retaliation, infiltrated Indian airspace on February 27 but their attack was foiled by IAF, which quickly scrambled jets.

While IAF's Wing Commander Abhinandan Varthaman was captured in the dogfight by Pakistan, he had to be released due to mounting international pressure.

Despite Pakistan Prime Minister Imran Khan plea for peace, ceasefire violations by Pakistan are now occurring frequently.
