"It's obviously very sad. It recalls painful memories of our own experience with Jul 22, the most difficult moment in the post-war period in Norway."
NOT IN MY DAUGHTER'S NAME
The mother of an 11-year-old Swedish girl killed in a 2017 militant attack expressed shock after the New Zealand gunman said one of his motivations was to avenge her death.
The attack "goes against everything Ebba stood for," Jeanette Akerlund told Swedish public television SVT.
Another person flagged by the Christchurch shooter was Luca Traini, an Italian jailed for 12 years over six non-fatal racist shootings in 2018, whose name was reportedly engraved on one of the guns.
But Traini's lawyer Gianluca Giulianelli told Italian radio his client "would certainly distance himself from this tragedy ... because he has ... a strong feeling of repentance for what he did."
'ODIOUS BUT NOT MY FAULT'
Writing on Twitter, Italy's far-right Interior Minister Matteo Salvini condemned the attacks but also said he pitied those who would blame him for the bloodshed.
"Massacre in #NewZealand, condemnation and utter contempt for the odious murderers, prayers for the innocent victims, compassion for those who say 'it's always Salvini's fault'," he tweeted.
Elsewhere, Dutch far-right MP Geert Wilders, who is known for his outspoken anti-Islam views, said such violence was never acceptable.
"These are shocking images. It is always sick to see people use violence, whoever you are and whatever you may think," he told public broadcaster NPO.
"You never use violence ... This is simply inhuman."

At Friday prayers in Jerusalem's Al Aqsa mosque, Grand Mufti Muhammad Ahmad, the city's highest Muslim authority, urged worshippers to hold special prayers for the victims of the attacks.
