Separate roadside bomb attacks in Afghanistan have killed at least three people including a child and wounded 20 others, Afghan officials say.
A Kabul police spokesman said a bomb explosion on Sunday targeted a police car, killing the driver and a nearby child as well as wounding five other civilians including children.
The majority of bomb attacks in the capital Kabul in recent months have been sticky bombs - explosive devices with magnets that are attached to vehicles and detonated by remote control or timer.
The second explosion was caused by a bomb placed in a crowded market in Helmand province, killing one civilian and wounding 15 others, a police spokesman said.
No group immediately claimed responsibility for any of the attacks. Afghan police officials said investigations were underway.
The Islamic State group's local affiliate has claimed responsibility for some of the attacks, but many go unclaimed, with the government blaming the Taliban. The insurgents have denied responsibility for most of the attacks.
Afghanistan has seen a nationwide spike in bombings, targeted killings and violence on the battlefield as peace negotiations in Qatar between the Taliban and the Afghan government have stalled. It's been over a month since the sides last met to discuss how to proceed.
