OSLO, Norway -- A Norwegian police official says the 32-year-old Norwegian man suspected of the Oslo bombing and a shooting at a youth camp does not appear to be linked to Islamist terrorism.

The official says the attacks probably have more in common with the 1995 attack on a U.S. federal building in Olkahoma City than the Sept. 11, 2001 attacks.

He says the suspect appears to have acted alone, and "it seems like that this is not linked to any international terrorist organizations at all." He added that the investigation is still ongoing and that things can change.

The official was speaking on condition of anonymity because that information has not yet been released by Norway's police.
