Canadian publication rabble.ca reports:
A gunman shot and very seriously wounded a Canadian Forces soldier at the War Memorial in Ottawa at about 10:00 a.m. this morning, Wednesday, October 22.
According to witnesses, the gunman then hijacked a car, without harming the driver, and drove onto Parliament Hill.
There are reports that the gunman then entered the main entrance of the Centre Block of Parliament and shot repeatedly and indiscriminately.
Journalists who were on the scene at the time report that some people there were gravely injured, but there are no details as to the extent of casualties yet.
Marc Soucy of the Ottawa Police said there were "numerous gunmen" responsible for what witnesses say were dozens of shots, according to CNN.
This footage from inside the Parliament Hill building was captured by a Globe & Mail reporter on the scene at the time:
