Jordanian officials say a fire at a Syrian refugee camp in Jordan has killed a Syrian man and two of his sons.

A third son was in critical condition at an Amman hospital.

The officials say 40-year-old Yassin Hariri and his boys — aged three and eight — died early on Tuesday, hours after a gas canister used for heating exploded and burned down their tent in the Zaatari camp. The officials spoke on condition of anonymity in line with regulations.

Dr. Ishaq Maraqa says the Hariris were brought to Mafraq Hospital late on Monday with "severe burns all over their bodies."

Zaatari is home to 120,000 Syrians who fled the war at home. After last week's storm, aid workers began distributing gas heaters to the refugees on Sunday.
