Speaking in a meeting of the Afghan high peace council, President Ghani said the attack was a clear declaration of war against the Afghan nation, insisting that those who claim responsibility for the attack are no more belonging to the Afghan society.
The Taliban group claimed responsibility behind the attack that left more than 100 dead and over 200 others wounded.
In the meantime, President Ghani insisted that the government and nation should succeed both in peace efforts and in the war against terrorists.
He said the time has come for the Taliban group and their supporters for a decision to choose from the two alternatives.
In regards to the peace efforts, President Ghani said a clear roadmap should be prepared for the peace process along with a clear perspective.
However, he said tendency towards peace process does not mean that the government will sit silent.
He said that there should be a distinction between those willing to participate in peace talks and those refraining from doing so, insisting that the doors will be closed who are not prepared for the reconciliation process.
President Ghani warned that those supporting violence and continued insurgency will be eliminated and the nation will take revenge of the atrocities.
