A roadside bomb exploded in the Afghan eastern province of Khost, killing at least 10 civilians traveling in a vehicle, officials say.
Interior Ministry spokesman Nasrat Rahimi said the blast occurred in the district of Ali Sher On the morning of December 17.
The casualties included three children, two women, and five men, Rahimi said.
Talib Mangal, a spokesman for the provincial governor, said they were all members of one family who were traveling to Logar Province to attend a funeral.
In the northern province of Balkh, officials said some 18 people were wounded when explosives attached to a bicycle detonated near a police vehicle.
The blast took place at one of the busiest intersections of the provincial capital, Mazar-e Sharif, said Adil Shah Adil, the spokesman for Balkh’s police chief.
He said six traffic police officers were among those wounded, while the rest were civilians.
No one immediately claimed responsibility for the two attacks, but officials blamed the Taliban, which controls or holds sway over half the country.
The United Nationals Assistance Mission in Afghanistan (UNAMA) has said it is "gravely concerned about the unprecedented levels of violence” harming Afghan civilians.
UNAMA recorded 2,563 deaths and 5,676 injured in the first nine months of this year.
