Prime Minister Manmohan Singh has condemned the assassination of the former Afghanistan President and Chairman of the High Peace Council, Burhanuddin Rabbani, saying the best tribute to his memory is to carry on with the process of reconciliation in the war-torn country.

In a letter to Afghan President Hamid Karzai, before his departure to attend the United Nations General Assembly session, Dr. Singh said the best tribute the people of Afghanistan could pay to the departed leader was to carry on with the task that he had begun — securing a peaceful and safe future for the people.

The Prime Minister recalled his two meetings with Rabbani in Kabul in May 2011 and in New Delhi in July. The veteran leader had apprised him of his vision of peace and reconciliation in Afghanistan, he said.
