Norway's Prime Minister Jens Stoltenberg, center, shakes hands with a survivor of the shooting at an island youth retreat, as he visited survivors and relatives at a hotel in Sundvolden, Norway, flanking the prime minister at right is the leader of the Labour party's youth group Eskild Pedersen who was on the island during the attacks, Saturday, July 23, 2011. The 32-year-old man suspected in bomb and shooting attacks that killed at least 91 people in Norway bought six tons of fertilizer before the massacres, the supplier said Saturday as police investigated witness accounts of a second shooter. Norway's prime minister and royal family visited grieving relatives of the scores of youth gunned down in a horrific killing spree on an idyllic island retreat. A man who said he was carrying a knife was detained by police officers outside the hotel, as the shell-shocked Nordic nation was gripped by reports that Norwegian gunman may not have acted alone.
