Militants who say they are holding three UN workers hostage in Afghanistan say they have split them up to make any rescue attempts more difficult.
The three were helping to organise the presidential poll on 9 October
There are conflicting reports about whether the militants have extended a deadline for a demand to free prisoners from Afghan jails and Guantanamo Bay.
Earlier they said they would kill the hostages if the demands were not met.
Filipino Angelito Nayan, Annetta Flanigan from the UK and Kosovan Shqipe Habibi were seized in Kabul last week.
A group calling itself the Army of Muslims say they carried out the abductions.
The hostages "are not in one location, they are in three different locations," the AFP news agency quoted a spokesman for the group, Akbar Agha, as saying.
The group says if the security forces find one of the hostages, the other two would be killed.
There has been no independent confirmation that the hostages have been separated.
The authorities in Kabul say they are still keeping an open mind as to who is behind the kidnappings.
The three hostages appeared unharmed in a video shown by Arabic TV on Sunday.
The UN in Kabul, confirming that the footage did show the UN workers, has appealed for their release, saying they all needed medical attention.
Afghan authorities arrested several people on Friday and Saturday they believe are linked to the kidnapping.
