Officials say a massive office building collapsed in a storm in downtown Washington.
Here are some questions we want answered.
The Washington Monument, the National Mall and the Lincoln Memorial are all visible from downtown.
The Capitol Building is visible on the left, the U.S. Capitol Building on the right.
Officials say the building was knocked down by heavy rains and then the building began to collapse.
The building collapsed on Monday night.
It is not known what caused the collapse, but the building is one of several structures in the downtown area that have suffered heavy damage from the storm.
The Associated Press reported that several workers were injured.
The Washington Post reported that the building had been a financial institution and that the collapse was due to the heavy rains.
It said the building, located on Pennsylvania Avenue, is a historic landmark.
More than 500 people were evacuated from the area, but those who stayed on their own were told to stay away from the rubble.
ABC News said that the Metropolitan Police Department had told the public that the Washington Monument was on fire, but no fire officials confirmed that.
