"But Pak PM deserves a chance since he has recently taken over. Of course the war rhetoric (in India) has more to do with the impending elections that anything else (sic)," she added.
Khan on Tuesday assured India that he would act against the perpetrators of the Pulwama terror attack if New Delhi shares "actionable intelligence".

Khan said that he understood it was India's election year and the narrative of blaming Pakistan would make it easier to get votes from the masses but he hoped that better sense will prevail and that India would be open to dialogue.
The suicide attack by Pakistan-based Jaish-e-Mohammad (JeM) terror group in Pulwama left 40 CRPF personnel dead.
