Four people were killed as a gunman opened fire inside an Oklahoma hospital, authorities said.
The gunman, described as 35 to 40 years old and armed with a rifle and handgun, appeared to have died from a self-inflicted gunshot wound.
Earlier, police captain Richard Meulenberg said officers were treating the scene as “catastrophic,” with “several” people shot and “multiple injuries.”
US President Joe Biden has been briefed on the Tulsa shooting, the White House said in a statement, adding that the administration has offered support to local officials.
