Party's spokesperson Kapil Sibal said it was "shameful" that the ruling BJP was organising "Vijay Parv" to celebrate its victory in the Delhi municipal polls at a time when Pakistan killed two of "our soldiers in our territory".
He also took a jibe at the government, saying it should "take off bangles and do something".
Sibal was referring External Affairs Minister Sushma Swaraj's offer to send bangles to Manmohan Singh when Indian soldiers were beheaded by Pakistan during the UPA rule.
He said the government can finalise a policy to deal with cross-border terrorism only if there is a full-time defence minister.
