Australian police say a knife attack in Sydney that wounded a bishop and a priest during a church service as horrified worshippers watched online and in person was an act of terrorism.

Police arrested a 16-year-old boy on Tuesday after the stabbing at Christ the Good Shepherd Church that injured bishop Mar Mari Emmanuel and a priest. Both are expected to survive.
