On Monday, Washington accused the group of assassinating prominent Afghan figures in the past weeks.
The accusation, which is being directed at the militants by Washington for the first time, comes as the Afghan government and the Taliban representatives are due to resume the US-brokered peace talks in the Qatari capital on Tuesday.
A prominent election activist, the deputy governor of Kabul province and five people working as journalists for news networks were among the Afghan figures assassinated in the past several weeks.
"The Taliban's campaign of unclaimed attacks and targeted killings of government officials, civil society leaders & journalists must... cease for peace to succeed," Colonel Sonny Leggett, spokesman for US forces in Afghanistan, said on Twitter.
