At least seven Syrian refugees were killed Wednesday in Jordan when a kerosene heater caused a fire in a refugee camp.

Civil defense officials say four other refugees were injured in the accident in a caravan in the King Hussein area in the northern city of Ramtha.

Jordan houses more than 200,000 refugees who fled fighting in neighboring Syria. Some of them are being hosted by families and some live in makeshift camps with kerosene heaters used to fend off the cold.
