A thick blanket of smoke engulfed east Delhi's Ghazipur dumping yard as a fire that broke out on Monday continued to rage on in some pockets even after 19 hours. Two fire tenders have been stationed at the spot and a total of 50 fire personnel along with 10 fire tenders were working at the spot last night. A senior fire department official said the blaze, which erupted last afternoon, has been brought under control. Firefighting operations are still underway and it might take a few more hours to complete the cooling process, Chief Fire officer Atul Garg said.
