Washington (CNN) -- More bullets struck the Pentagon in a shooting Tuesday than initially thought, officials said.
"It has been determined that at least six shots were fired," Steven Calvery, director of the Pentagon Force Protection Agency, said in a statement Wednesday. "As previously stated, two exterior windows were impacted by bullets. Upon investigation, it has been determined that four other bullets hit the Pentagon's facade".
Calvery said the investigation was ongoing and the FBI was evaluating evidence, including video footage from the Pentagon and surrounding buildings and roads as well as ballistics.
On Tuesday, Calvery told reporters he thought the shooting, which took place early Tuesday at the Defense Department's headquarters, was "a random incident".
"We are looking at all the possibilities," he said. "What we have is an isolated incident so far".
