Congress leader Priyanka Gandhi Vadra on Sunday condoled the deaths in a terror attack in Jammu and Kashmir's Ganderbal and said killing innocent civilians and spreading violence and terror among the people are crimes against humanity.

A doctor and six labourers were killed when terrorists struck a tunnel construction site on the Srinagar-Leh national highway on Sunday, officials said. The unidentified terrorists carried out the attack when the labourers and other staff working on the tunnel project at Gund in Ganderbal had returned to their camp late in the evening, they said.
