Government today said, it is closely monitoring the reports of Pakistan digging tunnels along its border in Sargodha district. External Affairs Minister S M Krishna said in New Delhi that both the Defence and External Affairs Ministry will work together to analyse its implications to India. He was reacting to media reports about Pakistan digging tunnels in Sargodha district of Pakistan's Punjab province close to the Indian border. <br/><br/>According to the report, the fact that these huge tunnels do not seem to be leading to any roads have raised suspicions that they may be used to store nuclear weapons or missiles. A senior official said, these clearly can't be meant for transport as is obvious from the images available
