At least 10 people were injured in a “catastrophic” explosion that trapped residents in a Maryland apartment building, authorities say.

A “mass casualty” event was declared after fire ripped through the building on Quince Orchard Boulevard in Gaithersburg at around 8.40am on Wednesday morning, Montgomery County Fire and Rescue spokesman Peter Piringer said in a live broadcast from the scene.

Ten people were taken to hospital, two in critical condition, Montgomery County Fire and Rescue Service chief Scott Goldstein told reporters.

Four children were among the moderately injured requiring hospital treatment, Mr Goldstein said.

Several other people remain unaccounted for, he said.

“The building has sustained a significant explosion, resulting in a structural collapse,” Montgomery County Fire and Rescue Service chief Scott Goldstein told reporters.

The neighbouring buildings have been evacuated and natural gas has been shut off, Mr Goldstein said.

More than 100 officers responding to the scene arrived to fund what were described as “heavy fire conditions”, Mr Piringer said.
