Trapped Indian workers face prolonged ordeal as drilling delays rescue

The rescue operation to save 41 workers trapped in a tunnel in Uttarakhand, India, has been delayed again due to a problem with the drilling machine. The machine is being repaired and drilling work is expected to resume on Friday. The workers have been stuck inside the tunnel for 12 days after a portion of it collapsed due to a landslide. Efforts to create an escape route for the workers involve drilling through debris and creating a micro-tunnel. The operation has been challenging due to the presence of rocks, stones, and metal in the debris. The timeline for the rescue operation remains uncertain.
