Former home secretary RK Singh, during whose tenure the investigation into the 26/11 Mumbai attacks was conducted and Ajmal Kasab was hanged, has said Tahawwur Rana's extradition to India is a very important development. Speaking exclusively to NDTV, Mr Singh said, "This also sets a template which will hopefully be followed in the future. If the world wants to actually wipe out terrorism, quick extradition is absolutely necessary."
