this is a shocking news, we cant understand how it happens. a machine can detect a currency note whether it is pure or fake? then why cant the security people cant find out the people are terrorist or human beings? how dare they can enter the country to spoil the whole economy of the country? the security measures should be tightened throught out the country in round the clock. those terrorists should be given immediate death punishment. the poor and innocent people lost their lives. wherever they may be they all should be caught and punished very soon.
