Mmmm...something is not quite right here. Two young boys DIG a hole, deep enough to cross over to India, and the grandfather says the boys 'mistakingly crossed over." What are they - the wandering sheep?
If one digs a tunnel deliberately and crawls out of it, it certainly cannot be referred to as "wandering mistakingly."
The Al Queda are known to have used children as young as 13 for doing their dirty work, and as suicide bombers. Whether these children have been brain-washed to do something illegal by the Pakistanis needs to be examined. It may just well be that the boys 'wandered' into India innocently. But then again, muslim terrorists are known to strap women and children with bombs on numerous occassions and send them on their merry way to do God's cleasing work on their behalf, so nothing is implausible in this crazy world.
