A portion of the ceiling at the Guwahati airport collapsed on Sunday as sudden rain battered the city. Operations were halted briefly and six flights were diverted after heavy winds wreaked havoc at the Lokpriya Gopinath Bordoloi International Airport. A video shows a group of passengers waiting outside the airport as a portion of the ceiling suddenly collapses overhead. No injuries were reported, airport sources said, adding that the collapse was caused by an overflowing outlet pipe and heavy winds.
