Explaining the delay in the ongoing rescue operation for 40 labourers trapped inside the under-construction tunnel which collapsed in Uttarakhand's Uttarkashi, NHIDCL Director Anshu Manish Khalkho said the delay was due to the fragile nature of the location.
Relief and rescue operations are underway for the sixth day on a war footing at Silkyara Tunnel, where 40 labourers were trapped following the collapse of the under-construction tunnel.
