LUCKNOW, India—Officials trying to reach 41 workers who have been trapped in a collapsed tunnel in northern India for eight days were contemplating alternative rescue plans Sunday after snags with a drilling machine caused them to halt digging.
A new drilling machine arrived at the accident site in Uttarakhand state on Saturday to replace one that was damaged while breaking through the rocks and debris. They had been using the drill to create a space to insert wide pipes through which the trapped workers could crawl to their freedom.
