Khan said the latest visit by the Taliban’s Political Commission delegation to Pakistan would further the talks. The prime minister urged all Afghan parties to actively reduce violence in the country.
Ghani said the ulema (Body of religious scholars) have confirmed that the war has no religious legitimacy. He further assured that Afghanistan had the support of the international community.
Ghani added that as a state and society, Afghanistan has demonstrated the commitment, compassion and courage to take hard decisions to start direct peace talks with the Taliban.
The council will have the final say and will ultimately decide on the points that the negotiating team takes up with the Taliban.
As many as 20 countries and international organisations including the United Nations participated in the 'Strengthening Consensus for Peace' meeting.
Ghani spokesman Sediq Sediqqi tweeted Sunday that a political deal between Ghani and Abdullah had been signed in which Ghani would remain president of the war-torn nation.
Speaking on condition of anonymity, an Aghan official told AFP that Abdullah has made a multi-pronged proposal to Ghani.
The Ashraf Ghani government has blamed the Pakistan-backed Haqqani network for the terror attack.
The agreement, which will initially see 100 prisoners freed each day, will depend on the Taliban's willingness to significantly limit attacks in the country.
Many of those who fled return to their seats after Ghani's refusal to leave the podium prompted cheers and applause.
His rival Abdullah Abdullah held a parallel inauguration that could plunge the country deeper into crisis ahead of peace talks with the Taliban.
Ghani also stressed that the Taliban are still engaged in drug trafficking while discussing the issue with the US Congressional delegation.
The president said his office had cleared "all obstacles" to peace with the announcement following consultations with religious scholars, political parties and civil society groups.
The Taliban had taken control of part of Bulcheragh district and more than 50 government forces were missing, he added.
Modi was referring to the Afghan president's peace initiatives including a surprise announcement of a week-long ceasefire with the Taliban for Eid.
