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.
What kind of explosion was that? Someone blowing themselves up with explosives on purpose, or explosive fumes/gases from a drug lab or something igniting?
Any idea what they were looking for with that search warrant?
Big fireball and low velocity implies gasoline or natural gas. A drug lab is possible, but not an explosive like semtex or anfo.
My guess is they turned on the stove unlit and were hoping to take out some cops.
