Three persons who went to watch the air show at Chennai’s Marina Beach have died. Doctors said at least one of them had heat stroke.

Enthusiastic families had gathered at the Marina beach before 11 am to witness the air show on the occasion of the 92nd IAF Day celebration. Many were seen shading themselves from the blinding sun with umbrellas. 

The air show had included a show by the Special Garud Force commandos in a simulated rescue operation and in freeing the hostage.
