- Dozens injured as wall toppled outside building
- At least 50 deaths as shock is also felt in India and Tibet
- Mudslides block access to worst-affected remote areas
The 6.9-magnitude quake damaged buildings and sent residents in the Nepalese capital Kathmandu running into the streets.
It struck at 6.10pm local time yesterday and was felt also across northern and eastern India and in the capital New Delhi.
In Nepal the government said seven people had died and more than 70 were hurt. Among the victims were two men and an eight-year-old girl, who were killed when a brick wall toppled outside the British Embassy in Kathmandu.
The full extent of the damage is not immediately known because the worst-affected areas are remote and sparsely populated. Parts are now cut off by mudslides triggered by the quake.
The quake triggered at least two aftershocks of magnitude 6.1 and 5.3, and more are possible, experts have warned.
