An 11-year-old boy is in critical condition after an explosion in Mount Laurel Township Monday night.

It happened along Ramblewood Parkway around 6:15 p.m.

Authorities say the boy and another 10-year-old were in the backyard of the house with a bonfire. He picked up a gas can and started pouring on the fire when the can exploded.

He was flown to the hospital with head-to-toe burns.

The 10-year-old is apparently OK.
