Home Ministry spokesperson Laxmi Prasad Dhakal said: "It has already been one week since the disaster.
"We are trying our best in rescue and relief work but now I don't think that there is any possibility of survivors under the rubble."
Meanwhile, the death toll from the earthquake rose to 6,624 [Nepal quake toll rises to 6,624]. In the past week many survivors were pulled out from the rubble by rescue teams.
India on the other hand, continued to assist Nepal in all rescue and relief operations. India sent many supplies such as food packages, tents, clothes for the victims of the quake.
Most people in Kathmandu have moved back into their houses a week after the earthquake struck. 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.
