A bomb blast and a shooting attack in Kabul on December 15 killed at least three people, including a deputy provincial governor, officials said.
Afghan Interior Ministry spokesman Tariq Arian said a sticky bomb attached to an armored vehicle belonging to Kabul's deputy provincial governor, Mahbobullah Mohibi, killed two people and wounded two others.
Mohibi was killed alongside his secretary while two of his bodyguards were wounded, Arian said. The bombing took place in the Macrorayan neighborhood of Kabul.
In the other attack, gunmen killed a police officer and wounded another policeman in the Bagrami district of the capital, said Ferdaws Faramarz, spokesman for Kabul's police chief.
No one immediately claimed responsibility for the Kabul attacks. The Islamic State (IS) group has claimed responsibility for multiple attacks in the capital in recent months, including attacks on educational institutions that killed as many as 50 people, most of them students.
Taliban militants have waged bitter battles against IS fighters, particularly in IS strongholds in eastern Afghanistan, while continuing their war against Afghan government forces.
Since September, the Afghan government and Taliban militants have been holding peace talks in Qatar aimed at ending decades of war.
Despite the peace talks, violence has continued unabated.
On December 14, Afghan government officials announced that the talks will resume early next month as the warring sides take a break after reaching agreement on procedural ground rules for sustaining their dialogue to end the war.
"We're taking a break for now and will be ready to discuss the agenda when talks resume," said an unnamed senior Afghan official overseeing diplomatic communications with the Taliban.
The talks came after the United States and the Taliban struck a deal in February on the withdrawal of the remaining 12,000 U.S. troops in exchange for Taliban security guarantees and a commitment to peace negotiations.
