NEW DELHI: Heavy rains wreaked havoc in the national capital on Thursday, claiming three lives within 12 hours and leaving parts of the city paralysed by waterlogging, fallen trees and traffic chaos.In southwest Delhi’s Vasant Vihar, two boys died after a wall collapsed on them in Basant Nagar near Hanuman Mandir around 4:40 pm. Police said they received a call about the incident and rushed to the spot along with a disaster management team.A 10-year-old boy from Begusarai, Bihar, and a 9-year-old boy from Madhubani, Bihar, were pulled from the debris and taken to AIIMS Trauma Centre in PCR vans. Both of them were declared dead upon arrival, deputy commissioner of police (Southwest) Amit Goel said.Police said the boys were sitting on stairs next to the wall when it suddenly collapsed. According to the DCP, the wall, owned by the Delhi Development Authority (DDA), is suspected to have been weakened by prolonged rain and waterlogging in the area.Police said the debris was being cleared to prevent any further inconvenience. They added that the DDA had been informed and would conduct a detailed inspection to assess the structural safety of surrounding walls. The bodies have been kept for post-mortem, and legal formalities are in progress.Earlier in the day, a massive old neem tree uprooted and fell on vehicles in South Delhi’s Kalkaji area, killing a man and injuring his daughter. The incident took place around 9:50 am in B-Block, where Sudhir Kumar, 50, and his daughter Priya, 22, were riding a motorcycle that got crushed under the fallen tree.Both were rushed to Safdarjung Trauma Centre in critical condition, but Kumar could not survive. Priya suffered a pelvic fracture and is undergoing treatment.Authorities have urged residents to remain cautious as heavy rains continue to lash the city, bringing down trees, flooding streets and disrupting normal life.After the rain-related deaths came to light, AAP leader Atishi called for the resignation of Delhi PWD minister Parvesh Verma, holding him responsible for the deaths and accusing the BJP government of failing to prepare for the monsoon.“This is not the first such death, the toll from rain-related incidents has now risen to 20. Who is responsible for this?” she asked, talking to PTI. She alleged that there had been no preparation for the rains, which had led to widespread waterlogging, trees collapsing and vehicles getting stuck in underpasses.“Parvesh Verma must take responsibility and resign. If he is not resigning, chief minister Rekha Gupta should remove him from the post,” she said.She called the situation in the national capital the result of the “failure of BJP’s four engines.”Atishi further claimed that even with all powers in its hands, the ruling party had failed to safeguard citizens during the monsoon.
