2 Saskatchewan girls killed in fire

Two young girls have died in a house fire near Hudson Bay, Sask.

The fire broke out Monday some time before 1:30 p.m. CST on an acreage about three kilometres north of the town.

The RCMP said when fire and other emergency crews arrived at the scene, the mobile home was completely engulfed in flames and three adults were outside.

"The goal of all of us was to rescue," RCMP Sgt. Darren Simons told CBC News Tuesday. "But upon my arrival ... we knew there was nothing we could do to get in the residence."

One woman at the scene, who was visibly distraught, had suffered injuries in the fire, the RCMP said.

When the fire was out several hours later the remains of two girls, twins just under three years old, were found.

The home was destroyed.

The girls' grandmother, Jean Lewis, confirmed to CBC News that the twins, Dinika and Lilyanna, died in the fire.

The pastor at the Pine Ridge Fellowship in Hudson Bay told CBC News that he visited the girls' mother in hospital.

"The mother was in the hospital and fairly heavily medicated. Not so much because of the physical part of it, but because of the emotions that are involved and the trauma that she had been through," Fred Buhler told CBC News Tuesday.

Community members have been collecting donations to help the family.

The fire is under investigation.

Hudson Bay is in east-central Saskatchewan, about 210 kilometres north of Yorkton.
