Dressed in his brother's old British Army fatigues, Mohan Ghale is rebuilding his mother's home stone by stone, after returning to Barpak village, high in the Himalayas, which was demolished by last month's earthquake.

Ghale had been working as a plumber a full day's journey away in the Nepalese capital, Kathmandu, but with his brother overseas and father away for work, it fell upon him to remake the family home at the epicenter of the magnitude-7.8 quake that killed 8,633 people nationwide.

"I came back to rebuild and to help my mother. I had to," said the 30-year-old, who put off the promise of a job in Japan to return to the rubble of his childhood home.
