An overnight explosion at the US embassy in Oslo may have been an act of terrorism, Norway's police have said, BBC reported.
The embassy in the Norwegian capital sustained minor damage after the blast in the early hours of Sunday - but no-one was injured.
"One of the hypotheses is that it is an act of terrorism, but we are not completely locked into it," Frode Larsen, the head of police joint investigation and intelligence unit, told Norway's public broadcaster NRK, according to BBC.
