Before the blast in Arlington, Virginia, police said someone from inside the house had fired shots as officers tried to enter.
Police said earlier they had responded to reports of someone firing a flare gun from a residence on Monday night.
Officers on the scene reported only minor injuries.
But it is not clear if the suspect was injured or apprehended.
Some residents in the surrounding area said on social media they felt their homes shake.
I’m just imagining the one lieutenant calling the courthouse as the fireball rises into the air above the property “hey, we might want to add unlawful possession of low yield explosives to the list of charges, no we haven’t entered the property yet, yes I’m sure.”
