Police in Virginia on Wednesday responded to reports of a man with a weapon at an office building in suburban Washington, occupied by USA Today and its publisher, Gannett.

The police said they had responded to a call reporting that a man with a weapon had entered the building.

No gunshots have been reported, and the authorities say they have not found "evidence of any acts of violence or injuries."

As a precaution, the occupants of the building were evacuated as the police combed the building in search for the possible gun wielding person or any suspicious items.

The U.S. has been marred by incidents of mass shootings lately, with the last two leaving 31 people dead in Texas and Ohio.

The shootings saw the number of mass shooting in the U.S. in 2019 hit 251, with more than four months until the year ends.

President Donald Trump condemned the shootings, saying such incidents had no place in the country.

"In one voice, our nation must condemn racism, bigotry and white supremacy," President Trump said on Monday. "These sinister ideologies must be defeated. Hate has no place in America."

The rise in mass shooting incidents comes at a time when fresh calls for tighter gun control laws have emerged.

New Jersey Senator Cory Booker has expressed his support for the calls to avail stricter gun laws, saying the U.S. seems to be “accepting the idea that these [shootings] are going to be a regular occurrence”.

Trump on his part said various government agencies must work together to identify individuals who may commit violent acts and prevent their access to firearms.
