A gas explosion killed a least 7 in the Italian town of Ravanusa, Sicily late Saturday. 

Authorities reported that four individuals were found Monday at dawn and 2 remain missing.

On Sunday, two women were found buried alive under the rubble after dogs sniffed them out.

Four houses were demolished and three others were damaged in the explosion on Saturday, with authorities reporting that a gas leak had most likely caused the explosion. Authorities reported, however, that an investigation had been initiated to investigate the true cause of the explosion.

Ravanusca's fire service Tweeted a photo of firefighters standing on the debris.

Italgas, the gas grid operator, expressed its condolences to the residents of Ravanusa, stating that it had not received any reports of any gas leaks.

The company stated that the distribution network was "fully inspected in both 2020 and 2021."

Firemen and civil rescuers Sunday tried to help find survivors in the town of 11,000.
