The parents seems to be lieing - had the kids not returned from School, on searching, simultaneously did they lodge a police complaint in pakistan?
Is it possibile for the kids to dig such a big manhole under the fencing in one day and cross the border...in that case, thousands can cross the border every day digging at several places
if they had run away from home, then why the hell they have to cross the border...are there no other place in pakistan for them to go around?
everything seems to be misterous in this....India should not release these kids, may be they were coming to deliver some message or information to the terror outfits.
