He termed it as mischief to suggest that tension was cropping up between the two countries and that could fizzle out his plan to visit New Delhi.<br/><br/>There have been a series of ceasefire violations along the LoC in Jammu and Kashmir by Pakistan which has resorted to mortar shelling of Indian areas over the past two days.
