Antisemitic screed says 19-year-old was motivated by New Zealand mosque massacres and Pittsburgh synagogue shooting

• Full report: one dead and three injured in synagogue shooting

The 19-year-old California man detained by police after a hate-motivated shooting at a synagogue near San Diego claimed to have been motivated by the deadly attack on two mosques in New Zealand last month.

Police in the US said the gunman, named as John T Earnest, opened fire inside the synagogue in Poway, about 30 kilometres north of San Diego, killing one person and injuring three others including a rabbi.
