An earthquake hit the area at around 08:37 local time, Nepal's foreign minister Shishir Khanal tells parliament, citing preliminary information.
He says the earthquake then triggered an avalanche, which in turn resulted in flash floods. He notes that teams are still verifying the information.
Khanal says that as well as Nepal, China is also experiencing "huge damage".
He says Nepal is co-ordinating with China. So far, 26 police personnel, nine armed police personnel and 44 military personnel are missing.
Officials from customs and immigration are also missing, he adds.
There has also been huge damage on road, bridges, communication and hydropower infrastructures. Rasuwa and Nuwakot were worst affected districts, he adds.
