INNISFAIL, Alta. — A central Alberta wildlife rescue centre says eight birds that were being rehabilitated were targeted and shot last week.

A Facebook post by the Medicine River Wildlife Centre says six crows and two ravens were found Friday morning, shot inside one of the facility's outdoor flight pens.

It says two birds were clinging to life while the others were already dead.

The non-profit centre, located southwest of Red Deer, cares for about 1,300 animals annually.

The post says staff and volunteers fear for their own safety following the incident.

Officials say police are investigating.
