A 101-year-old man has been pulled alive from the rubble of his house in Nepal, seven days after it collapsed in a deadly earthquake.

The man was rescued on Saturday and is now in hospital, according to Arun Kumar Singh, a local police official.

On Sunday two women and a man were rescued alive in the country's north-east.

"Kanchan Khatri, Gyan Kumari Khatri, and Dhan Kumari Khatri were rescued by security forces (on Sunday) at Kerabari village in the Syauli area," Ram Bahadur Nepali, a police officer in the north-eastern district of Sindhupalchowk, told DPA.

He said two of them were buried under a collapsed mud house, while one was pulled from under the earth after being swept by a landslide triggered by the earthquake.

They have been evacuated to the district hospital.
