He was an honest man besides being a father, brother and a Kashmiri." 'There is no doubt that the handlers across the border are trying to disturb peace here and they are not sending money here to build hospitals, roads and other things, but to support terrorism."

We will create such a situation when no one will be ready to help the handlers from the across the border,' the DGP asserted. /IANS
