(CNN) — Sixteen children and a teacher in Pakistan were killed Saturday after a gas canister used to fuel a school minivan exploded on a hot spring day, police in Gujrat said.

The blast injured 10 other people, according to Nadeem Ulla, a local police official.

“It’s over 100 degrees (38 degrees C), the heat probably caused the explosion,” Ulla said. “We do not expect any foul play “.
