A natural gas leak may have caused a house explosion in Saskatchewan on Wednesday.

RCMP say the responded to the call around 2:30 p.m. in Regina Beach, located about 50 km northwest of Regina.

"There has been a gas explosion on the corner of 1st Ave. East and 2nd Ave (beside the Post Office)," the Town of Regina Beach posted on its Facebook page. "Please stay away from the entire area!"

A photo posted on Twitter by a user named Shannon showed massive damage to a property, where pink fibreglass insulation, pieces of roof tile, bits of lumber and other debris are strewn all over the spot where a house used to be, and even in the trees. The post office next door also shows significant damage.

"It’s gone. It’s literally ground level from what I’ve heard. Basically all the walls gone. The roof is in the trees somewhere," Mark Obershaw, who owns the home that blew up, told CJME radio.

The town declared a state of emergency at 5 p.m. local time, to allow more access to emergency services and assistance, a Facebook post stated.

Dave Burdeniuk of SaskEnergy told the radio station there an underground gas leak and gas to surrounding buildings has been shut off.

There were no reports of injuries.
