Gunmen shot Toofan Omar, the station manager of Paktia Ghag radio and an officer for NAI, a rights group supporting independent media in Afghanistan, in a targeted killing in the capital on Sunday.
"Omari was killed by unidentified gunmen...he was liberal man...we are being targeted for working independently," said Mujeeb Khelwatgar, the head of NAI.
Officials in Kabul suspected Taliban fighters had carried out the attack.
Last month the NAI report at least 30 journalists and media workers have been killed, wounded or abducted by militant groups in Afghanistan this year.
In southern Helmand province, officials said Taliban fighters had seized a local journalist, Nematullah Hemat, from his home in Lashkar Gah, the provincial capital, on Sunday.
"There is just absolutely no clue where the Taliban have taken Hemat...we are really in a state of panic, said Razwan Miakhel, head of private TV channel, Gharghasht TV where Hemat was employed.
A Taliban spokesperson told Reuters that he had no information on either the killing in Kabul or the abducted journalist in Helmand.
A coalition of Afghan news organizations have written to U.S. President Joe Biden and leaders in the House of Representatives, urging them to grant special immigration visas to Afghan journalists and support staff.
