Four people were killed on Friday morning when a house collapsed in New Delhi following heavy rains and strong winds that affected flight operations and disrupted traffic due to waterlogging in many parts of the national capital.
Three flights were diverted and over 200 flights were delayed at the Delhi airport as thunderstorms and gusty winds disrupted operations.
An official said two flights that were to land at the Delhi airport were diverted to Jaipur and one to Ahmedabad.
More than 200 flights were delayed, according to data from flight tracking website Flightradar24.com.
Three children and a woman died after a house collapsed in Delhi, where a red alert has been issued by the India Meteorological Department (IMD).
"We received a call regarding a house collapse in Kharkari Nahar village in Najafgarh at 5.25 am. We deployed multiple teams on the spot and four people were rescued from the rubble," a Delhi Fire Services official said.
They were rushed to a nearby hospital where they were declared dead, he said.
"We have informed police about the matter," he added.
Visuals from several areas showed uprooted trees and people stuck in waterlogged roads. Videos surfaced on social media that showed a car half-submerged on Minto Road.
