Separate attacks on Wednesday, as violence continues amid speculation Taliban and Afghan government talks may be delayed further.
At least two people have been killed in a bomb attack that was followed by a shooting in Kabul.
Unknown gunmen shot and killed Mohammad Yousuf Rasheed, the head of an independent Afghan elections watchdog on Wednesday, said Ferdaws Faramarz, a spokesman for Kabul’s police chief.
The shooting took place when Rasheed, the executive director of the NGO, Free and Fair Election Forum of Afghanistan, was on his way to work.
His driver was wounded and taken to hospital, Faramarz said.
In a separate attack, a police vehicle was targeted by a sticky bomb in the eastern part of the capital.
The blast killed one police officer and wounded two others, according to Faramarz.
No one immediately claimed responsibility for the attacks.
The ISIL (ISIS) group claimed responsibility for an attack in Kabul a day earlier in which a roadside bomb tore through a vehicle, killing five people, three of them doctors on their way to work at the city’s main prison.
Among those killed in Tuesday’s attack was Nazefa Ibrahimi, the acting health director of the prison. Another doctor was in a serious condition.
Another targeted attack. Another assassination. Another civil society leader, Yousuf Rashid. These incidents don’t seem to be accidental. All those killed have something in common: they have voice & platforms & speak against violence & totalitarianism & for rights & freedoms.
