'A rare moment of joy': Nepal tunnel rescues give hope for more flood survivors

Two people have been rescued from a tunnel in Nepal more than a week after flash flooding hit the Nepal-Tibet border, killing more than 1,300 people. Nepal's army is continuing its search for survivors, but mud and rocks are making rescue efforts difficult. The BBC's South Asia correspondent Azadeh Moshiri, reporting from Nepal, describes how the rescues have given renewed hope to some families still waiting to find out what happened to missing relatives.
