Special Secretary in Relief and Disaster Management department Jason Shimray told PTI that rescue efforts with NDRF help was on.
Apart from the ten persons, four bodies have been extricated from the debris at Zoumol by an NDRF team so far while five persons are still missing, he said.
He said the ten have been taken to safe places following their rescue while the death figure at remote Zoumol village on Indo-Myanmar border due to the landslide "is likely to be revised".
Singh, when contacted over telephone today, told PTI that the landslide toll of 20 given by him on August 1 was based on report of the Zoumol village authority to the police.

"I am awaiting the official report from the field," the SP added.
The village is located on Khenjoi hills about 96 kms from Tengnoupa, the nearest town, of which 83 km is motorable. The massive landslide covered about one-km stretch.
Another NDRF team comprising 45 personnel is coming by road from Guwahati via Kohima today to join the rescue work. The team is moving on foot in the absence of proper road communication. Incessant rains and location of the village on the stiff portion of a tall hill is impeding their movement, he said.
The location of the village is impeding excavation work too as it would not be possible to dig the debris manually or send heavy machinery like earthmovers to the spot, Shimray, who sent a report to the Union Home Ministry during the day, added.
