Three people were pulled alive from the rubble of their home eight days after Nepal's devastating earthquake, as a supply logjam threatened to hamper disaster relief efforts bolstered by the arrival of U.S. aircraft and troops.

The small-scale rescue, announced on Sunday by a home ministry official, brought fresh hope to a badly-hit district northeast of the capital Kathmandu, but about 50 bodies were also discovered on a northern trekking route obliterated by an avalanche that the April 25 quake triggered.

That increased the death toll to 7,059, and the figure was likely to rise further as an entire village was carried away by the same avalanche and scores more people — both locals and foreign trekkers — were missing, officials said.
