While some hailed the decision to hang him, others were against it. Here are some reactions.
Narendra Modi: Better late than never
Digvijay Singh: The decision taken by the central government on Afzal Guru was taken after considering legal and constitutional provisions.Anyone who tries to incite violence in the name of religion needs to be dealt with severely.
Arun Jaitley: Public opinion has compelled the Government to act and enforce the law. India must today, as it did on 13th December 2001 speak in one voice and give a clear message to the world that India is not a soft state and those who attack India, its’ sovereignty and its institutions, will be held accountable. Though belated, Justice has been done.
Najma Heptullah: It doesn't matter what caste or creed the terrorist belongs to, he should be punished. My body guard was shot. I welcome the news. Whatever the law says, we must do that.
Rajiv Pratap Rudy: It is the right thing. We welcome the decision. The people of the country were waiting for it. Government has been forced to act under public pressure.
Yashwant Sinha: The credit of punishing Afzal Guru goes to the President and not the Central government.
Sushil Kumar Shinde: It is not a political move, but the law has taken its course.
Sharad Yadav: I am happy that justice has been done with the families of the martyrs.
PDP spokesman Nayeem Akhtar: PDP is disappointed at the hanging of Afzal Guru. We had urged that political sensitivities should be taken into considering while taking a decision on his clemency plea.
Kiran Bedi: Law finally turned full circle.
Afzal Guru's wife Tabassum: We do not wish to make it a political issue in an atmosphere which is already volatile but the family members, as citizens of India, have a right, which must be respected.
Supreme Court advocate Kamini Jaiswal: The question is when there are doubts and when the conviction is purely on circumstantial evidence what is the need for the hurry in carrying out the sentence? Only to get political mileage given elections are round the corner.
Amitabh Bachchan: The law should be followed and respected by one and all. Whatever has been done, it has been done according to the law — whoever the accused may be - you, me or someone else.
