Denouncing the blast outside the Delhi High Court as a "cowardly act of terrorist nature," Prime Minister Manmohan Singh on Wednesday asked all political parties to unite and crush the scourge.
"I just heard the sad news from Delhi about the bomb blast. I am told that 10 people have been killed. This is cowardly act of terrorist nature. We will deal with it. We will never succumb to the pressure of terrorism," Singh said.
He said "this is a long war in which all political parties, all the people of India have to stand united so that the scourge of terrorism is crushed".
"My heart goes out to the bereaved families and to those who are injured I convey my best wishes," he said in a statement to the Indian journalists accompanying him on his two-day visit here.
Singh said he has spoken to home minister P Chidambaram on the incident.
