Yousuf Rasheed, CEO of the Free and Fair Election Forum of Afghanistan (FEFA), was killed by unknown gunmen in Kabul city on Wednesday morning, his brother confirmed. 

The incident happened around 8:30am local time in the Tani Koot area in PD7 of Kabul city while he was on his way to the office and gunmen started shooting at his vehicle, Abdul Baqi Rasheed, his brother said. 

His driver was also wounded in the shooting and both were transferred to the Emergency hospital, but Yousuf Rasheed died, his brother said. 

Sami, Rasheed's driver, also died later at the hospital from wounds sustained in the attack, Sami's relatives confirmed.

Yousuf Rasheed was a very popular civil society activist.

Kabul police confirmed that Rasheed has died.

No group, including the Taliban, has immediately claimed responsibility for the attack. 

US Chargé d’Affaires Ross Wilson says Rasheed was a "dedicated and steadfast advocate for representative democracy in Afghanistan."

"He worked tirelessly for years to ensure free and transparent elections that engaged all Afghans. His death is a loss for his family, friends and nation," Wilson said.

"The United States condemns his assassination. He advanced an inclusive form of government for this country over the last 14 years. I am appalled by his murder, another in a cacophony of senseless and endless violence," Wilson added.
