Meanwhile, protests broke on Wednesday outside the Silkyara-Barkot tunnel in Uttarakhand's Uttarkashi as workers protested over the delay in rescuing 40 labourers who have been trapped inside after a portion of the under-construction tunnel collapsed on Sunday.
A portion of an under-construction tunnel between Silkyara and Dandalgaon on the Brahmakhal-Yamunotri national highway collapsed in the early hours of November 12, entrapping 40 labourers.
Relief and rescue operation is underway on a war footing at Silkyara Tunnel here, where 40 labourers are trapped following the collapse of the under-construction tunnel, an official said on Tuesday.
