OSLO (Reuters) - A bomb ripped through Oslo's central government district on Friday and a gunman dressed as a policeman then opened fire at a youth camp on a nearby island, killing at least 17 people altogether.
In the biggest attack in western Europe since the 2005 London transport bombings, seven died when the bomb exploded in the Norwegian capital in mid-afternoon scattering glass, shattered masonry and twisted steel across the streets.
Shortly afterwards, a gunman opened fire at the youth camp of the ruling political party on Utoeya island, north-west of Oslo. Police said at least 10 were shot dead as they fled shooting on the small, wooded island. The island was evacuated and police found undetonated explosives.
"I saw young people running around, jumping into the water," Kristine Melby, who lives across the narrow channel on the Norwegian mainland, told Al Jazeera television. "We heard people screaming."
The gunman, a 32-year-old Norwegian citizen, was held by police. The double attack bore some hallmarks of al Qaeda but analysts suggested right-wing militants might also be responsible.
"I have a message to the one who attacked us and those who were behind this," Norwegian Prime Minister Jens Stoltenberg said in a televised news conference. "No one will bomb us to silence, no one will shoot us to silence."
