At least 35 people have been killed and dozens wounded after a car bomb struck a bus carrying government employees in western Kabul.
"The car bomb hit a bus carrying employees of the ministry of mines during rush hour," an interior ministry spokesman told AFP.
The Taliban earlier said it had carried out the attack in the western part of Kabul.
Police cordoned off the area, located near the house of deputy government chief executive Mohammad Mohaqiq in a part of the city where many of the mainly Shia Hazara community live.
Today's suicide bombing was yet another example of the unrelenting violence in Afghanistan.
The Taliban, which is battling the Western-backed government and a NATO-led coalition for control of Afghanistan, has launched a wave of attacks around the country in recent days.
The UN Assistance Mission in Afghanistan (UNAMA), which has been documenting civilian casualties since 2009, said in its recent report that 1,662 civilians were killed and more than 3,500 injured in the first six months of the year.
Many of those deaths happened in a devastating single attack in Kabul in late May when a truck bomb exploded, also during the morning rush hour, killing more than 150 people and injuring hundreds.
UNAMA put the civilian death toll at 92, saying it was the deadliest incident to hit the country since 2001.
The bloody toll for the first six months of 2017 has unsettled the government of President Ashraf Ghani, who has come under increasing pressure since the May attack in Kabul.
Protests and deadly street clashes hit the Afghan capital in the wake of the May attack as people incensed by security failures called for his government's resignation.
