At least 225 Islamic State militants plus their families have surrendered in the Nangarhar province during the past two weeks.
190 women and 208 children surrendered alongside the fighters, after Afghan security forces launched a military operation against IS, in the Achin district.
Footage from Jalalbad on Sunday shows ranks of the former fighters as well as weapons they handed in.
According to Nangarhar Governor Shamahmod Miakhil "Most of them [are] from Pakistan and other foreign countries."
"Some of them who [are] still fighting will surrender soon," Nazar Ali Wahidi, Commander of the Nangarhar National Directorate of Security, added.
