Congress leader Priyanka Gandhi Vadra on Thursday cited remarks by rat-hole mining experts, who played a key role in the rescue of 41 workers trapped in Uttarakhand's Silkyara tunnel, to underscore that the country is built on love, reported news agency PTI.

All the 41 workers were rescued on Tuesday evening after 17 days of a multi-agency operation conducted by central and state governments. A 12-member team of rat-hole mining technique experts were called on Sunday to do the drilling after an American auger machine came across hurdles while clearing the rubble, reported PTI.
