Tayeng further said that the state is in constant touch with the Home Ministry for more information on the situation from the Chinese government.
“We have asked for more information on the magnitude of the blockade and the size of the lake. We are hopeful of getting more information from satellite or the Chinese side tomorrow,” Tayeng added.
He also said that no detailed information was available regarding the magnitude of the landslides or the lake formed due to the blockade. “The height of the barrier could not be ascertained, which could have provided an estimate of the water collected or the threat of the lake.”
