A large fire hit the Embassy of Ecuador in D.C. overnight, leaving two firefighters in the hospital, according to authorities... D.C. Fire and EMS officials reported the two-alarm fire around 12:23 a.m. Wednesday at a building at 15th and Euclid streets NW... Officials say the cause of the fire remains under investigation but sources tell ABC7's John Gonzalez that it appears to be accidental. Furthermore, the embassy is a diplomatic compound, which means the US Secret Service is assisting with the investigation. In 2011, the embassy was also damaged when a 5.8 earthquake hit the D.C. area.
