Police investigate gas explosion


Police are investigating the cause of Saturday's gas explosion in a Prague restaurant which killed two people and injured four others. The blast shook the three story apartment block early on Saturday morning, demolishing the ground floor where several restaurant employees were working and shattering windows in the upper storeys. Fifteen residents were evacuated, while emergency crews used sniffer dogs to find people trapped in the debris. Investigators say it is likely that a gas pipeline may accidentally have been damaged during work in the building.
