The Canberra Muslim Community has condemned the "barbaric killings" at mosques in Christchurch and has called for respect and support.

The wider community has rallied, placing flowers and notes outside mosques and the New Zealand High Commission in Canberra. Other religious leaders and politicians have expressed their sympathies directly to the Muslim community and in posts on social media.

A post on the Gungahlin Mosque Facebook page on Friday evening said the Canberra Muslim Community "condemns in the strongest possible terms the shootings and killing of innocent Muslims" in New Zealand.

"We condemn terrorism in all its forms, regardless of its source, and that terrorism has no religion and no homeland."
