A gas canister used to fuel a minivan exploded on a hot spring day in the Pakistani city of Gujrat on Saturday, police said. The blast killed 17 children and injured 10 others, according to Nadeem Ulla, a local police official. "It's over 100 degrees (38 degrees C), the heat probably caused the explosion," said Ulla. "We do not expect any foul play ". Compressed natural gas is used as an alternative fuel to gasoline because the engines are more energy efficient and cheaper to run, according to a report of CNN.
