"The death toll has reached 6,624," said the Home Ministry's national disaster management division. A further 14,025 people were injured in the quake, it added.

A fresh 4.5-magnitude aftershock on Saturday morning triggered panic among the people, who scrambled for open spaces. The 7.9-magnitude quake last week left a trail of devastation and suffering, with people spending the cold night in the open because of fears of fresh quake.

Nepal's remote mountainous areas have suffered "almost total devastation" from the powerful quake, aid agencies have warned, even as relief slowly began to reach far-flung regions amid fresh aftershocks that kept people on edge.

International humanitarian bodies have called for greater urgency in relief efforts. "One of our teams that returned from Chautara in Sindupalchowk district reported that 90 percent of the homes are destroyed. The hospital has collapsed, and people are digging through the rubble with their hands in the hope that they might find family members who are still alive," said Jagan Chapagain, Director of Asia Pacific with the IFRC.

"We can expect the situation to be the same if not worse in many other places where aid has not yet been delivered," Chapagain said. There are estimates that up to 40,000 homes in Sindupalchowk alone have been destroyed, the International Federation of Red Cross said in a statement.

Also, over 1,000 EU citizens are still unaccounted for in Himalayan Nepal, diplomats said on Friday. The Europeans had mostly been climbing in the avalanche-hit Mt Everest region and trekking in the remote Langtang range near the epicentre of the quake.

People return to houses in quake-hit Nepal

Most people in Kathmandu have moved back into their houses a week after a deadly earthquake rattled Nepal claiming over 6,600 lives and displacing millions, media reported on Saturday.

According to sources, the people said that they were feeling safe to shift into their houses as no major quake or aftershock has been felt in the last three days, local news reported.

However, thousands of others, whose houses have been completely damaged are still living in tents, vehicles and even under the open sky, while some are still reluctant to move to their homes, fearing another  quake.

"The past week has been the hardest days of our  lives. It is also becoming risky to live outside in tents due to health concerns. Many are feeling sick," Goma Shrestha, a resident from Kathmandu's Kalanki area said.

Occasional rainfall, coupled with poor food and sanitation in tents, have exposed people to diseases. Hospitals in Kathmandu have also witnessed a surge in the number of patients with flu-like symptoms.

Srestha and many of her relatives were staying under plastic tents for four nights. They had to live with little food and water as no relief assistance came from the government and other organisations.

Besides, nearly a million people living temporarily in Kathmandu city have returned to their villages.
