"I once again announce a ceasefire from tomorrow until the prophet's birthday provided that the Taliban reciprocate", said Ghani, referring to the Prophet Mohammed's birthday which Afghanistan celebrates on November 21.
The Taliban have been at war with the USA -backed Afghan government for nearly 17 years, and have stepped up attacks in recent years, seizing rural districts and carrying out major assaults against security forces and government compounds on an almost daily basis.
According to Mohammad Yusouf Ayubi, the head of the provincial council in Kunduz, the attackers stopped three buses on the road near Khan Abad district and forced the passengers to come with them.
"There were more than 100 passengers on the buses and they were taken to an undisclosed location".
The buses were travelling along a highway in an area under Taliban control, en route to the capital Kabul.
"We remain ready to support, facilitate, and participate in direct negotiations between the Afghan government and the Taliban", Secretary of State Michael Pompeo said in a statement Sunday.
The president, however, linked the ceasefire with similar announcement from the Taliban side and added sustainability of the truce belonged to the Taliban commitment.

All the passengers on the buses were from Badakhshan and Takhar provinces and were traveling to the capital, Kabul, said Abdul Rahman Aqtash, police chief in neighboring Takhar province.
Ghani made the announcement during celebrations of the 99th anniversary of Afghanistan's independence, a day after the leader of the Afghan Taliban said there would be no peace in the country as long as the "foreign occupation" continued.
Taliban sources said their leaders had also provisionally agreed a four-day truce during the annual Islamic feast of sacrifice, though supreme leader Sheikh Haibatullah Akhunzada still had to give his final approval.
The U.S. and North Atlantic Treaty Organisation officially ended their combat mission at the end of 2014 but have repeatedly come to the aid of Afghan forces in recent years to prevent the Taliban from advancing into major cities.
There has been a resurgence of the Taliban in recent years, with the insurgents seizing entire districts across Afghanistan and regularly carrying out large-scale bombings and attacks that have killed scores of people. The Taliban has reasserted itself this month with a wave of deadly attacks that have killed hundreds, providing it with additional leverage ahead of nascent peace talks.
In June, the Taliban observed a government ceasefire over the three-day Eid al-Fitr festival, leading to unprecedented scenes of government soldiers and militants embracing on front lines, and raising hopes for talks.
