The drilling process in the Uttarkashi tunnel collapse has been stopped yet again due to a technical glitch. This comes as a setback in the ongoing efforts to rescue the trapped workers. The drilling operation had previously faced several delays due to unfavorable weather conditions and challenging terrain. Authorities are working to rectify the glitch and resume the drilling process as soon as possible. The collapsed tunnel had trapped a total of 39 workers, out of which two have been rescued so far.
