A Russian newspaper has published grisly photos of 30 corpses it says were militants who took around 1,200 people hostage at a school in Beslan.
Kulayev is thought to be the only militant to survive the siege
Many of the faces in the photos, shown in the business daily Kommersant, were badly burned or mutilated.
Russian officials say 14 of the 30 have been identified, but Kommersant said not all of these were 100% certain.
At least 339 people died and more than 700 wounded as the siege ended in bloodshed nearly two weeks ago.
Publication of the photos coincided with the reopening of schools in Beslan for the first time since the tragedy amid high security.
The newspaper's printed version showed three rows of photos, accompanying an article on the identities of the militants.
Some of the faces were almost completely devoid of human features.
Officials say there were 32 hostage-takers altogether, but one suspect was arrested and the body of another was so badly disfigured as to be unidentifiable.
The captured man, Nur-Pashi Kulayev, has been able to identify only three other militants - his brother Khanpasha, and his fellow villagers Arsen Merzhoyev and Mairbek Shaybekkhanov.
Vladimir Khodov, a half-North Ossetian half-Ukrainian Muslim, has also been identified for certain by his fingerprints.
But Kommersant said there were problems with the fingerprinting of some of the other suspected militants, four of whose hands were too badly damaged to be tested.
In one case the prints of two suspects were mixed up, and many prints produced no matches when checked against police records.
This was the case with the corpse thought to be that of suspected ringleader Magomet Yevloyev, Kommersant said.
No relatives have come to identify the body, so it seems Yevloyev's participation in the hostage-taking may never be confirmed.
There is still doubt about the identity of another suspected ringleader, known as the Colonel and thought to be an Ingush by the name of Ruslan Khachubarov.
Khachubarov's body has not been found among the dead militants.
