Ghazni police spokesman says four policemen were also wounded.
A roadside bomb tore through a passenger bus east of the Afghan capital on Saturday, killing nine civilians, officials said, in the latest attack blamed on the Taliban.
Violence on the ground has spiked in recent weeks despite the Taliban and Afghan government holding peace talks in Qatar to end the country's grinding war.
The bomb struck the bus at around 10:30 am when it was travelling from Kabul to the eastern city of Ghazni, Waheedullah Jumazada, spokesman for Ghazni governor told the media.
"Nine civilians including three women were killed in the explosion," he said.
Four policemen were also wounded, Ghazni police spokesman Adam Khan Seerat said, blaming the Taliban for the attack.
Afghan civilians are being slaughtered on a daily basis.
Despite joining peace talks with the government last month, the Taliban have only increased violence in a bid to wield leverage in the negotiations.
The top US envoy to Afghanistan, Zalmay Khalilzad, said earlier this week that fighting is threatening the peace process.
On Friday, rights group Amnesty International said at least 50 people had been killed in attacks just in the preceding week, accusing the warring sides of failing to protect civilians.
"The world must sit up and take notice. Afghan civilians are being slaughtered on a daily basis," said Omar Waraich, Head of South Asia at Amnesty International.
"The international community must make the protection of civilians a core demand for their ongoing support of the peace process."
Afghan authorities also faced criticism this week after 11 children were killed in an air strike by the military that hit a mosque in the northeastern province of Takhar on Wednesday.
The authorities in Kabul insist that those killed were Taliban fighters operating in that area.
The events started with the detonation of a sticky bomb — a growing menace in Kabul, where insurgents and criminals slap magnetic bombs on the underside of vehicles.
Daesh said one of its fighters blew himself up at a "large gathering" in Kabul while others "detonated a parked explosives-laden vehicle" when security forces arrived, in a statement posted on the Telegram messaging app.
The bloodshed in the capital comes amid an ongoing surge in attacks across Afghanistan, where some 1,500 people were killed or injured last month alone.
