Over a dozen mortar shells slammed into different parts of the Afghan capital on Saturday, killing at least three people and wounding 11 others, an Interior Ministry spokesman said.
Heath Ministry officials put the death toll at five with 25 injured. There was no immediate explanation for the discrepancy in figures.
The shells were fired from two cars, Interior Ministry spokesman Tariq Arian said. No one took immediate responsibility for the early morning attack that also targeted the posh Wazir Akbar Khan area of the capital, which houses diplomatic missions.
The Taliban issued a quick statement denying any responsibility for the attack. The Islamic State affiliate also operates in the area and has claimed responsibility for recent assaults in Kabul including two devastating attacks on educational institutions that killed more than 50 people, many of them students.
As well as insurgent groups, there are several heavily armed warlords with militias living in Kabul with longstanding animosities against each other.
At least 3 dead, 14 wounded after bombing in Kabul
The mortar barrage comes as representatives of the Afghan government and the Taliban continued to hold talks in Qatar though progress has been slow. U.S. Secretary of State Mike Pompeo is expected to press for a reduction in violence in his meetings with both Taliban and government negotiating teams later Saturday during a daylong stop in Doha. The Taliban have mostly ignored such previous requests.
Hours before the attack rattled Kabul, a bomb attached to a car killed one security personnel and wounded three others in an eastern neighbourhood of the capital, said Kabul police spokesman Ferdaws Faramarz.
Violence in Afghanistan has spiked in recent months with increasingly horrific attacks often claimed by the Islamic State affiliate. Still the Taliban have been waging near daily assaults on beleaguered Afghan security forces.
There have been increasing calls for a cease-fire if peace talks are to continue. The Taliban have been steadfast in their refusal, demanding that any cease-fire be part of the negotiations.
