New Delhi, Feb 14 (IANS): Vice President M. Venkaiah Naidu and Union Minister Arun Jaitley on Thursday condemned the terror attack on a CRPF convoy in Jammu and Kashmir's Pulwama district that killed 30 troopers and left many injured.

Expressing shock over the attack, Naidu took to Twitter and wrote: "Shocked by the dastardly terrorist attack in which CRPF personnel were martyred. My heartfelt condolences to bereaved families and prayers for speedy recovery of the injured."

Naidu's remarks came after 30 CRPF troopers were killed when a van packed with explosives reportedly rammed into a CRPF bus on the Srinagar-Jammu highway near Lethpora town, about 30 km from Srinagar. Some 2,547 CRPF personnel were coming in a convoy of 78 vehicles from the transit camp in Jammu and headed to Srinagar.

Condemning the incident, Jaitley said the terrorists will be taught an "unforgettable lesson" for the heinous act.

"Attack on CRPF in Pulwama, J&K is a cowardice and condemnable act of terrorists. Nation salutes martyred soldiers and we all stand united with families of martyrs. We pray for speedy recovery of the injured. Terrorists will be given unforgettable lesson for their heinous act," Jaitley tweeted.
