Police in Norway's capital say the shooting at a mosque that wounded one person is being investigated as an attempted terrorist attack and that the alleged perpetrator is also a murder suspect in a separate case.
One suspect is in custody after the shooting Saturday at the Al-Noor Islamic Center in the Oslo suburb of Baerum. Police say they believe no one else was involved.
Oslo police official Rune Skjold told a news conference Sunday that the suspect, a man in his 20s, has been found to hold extreme right-wing views and animosity toward immigrants.
After the shooting, police went to his residence and said they found his 17-year-old sister dead. Police said the man is a suspect in that death.
