A soldier standing guard at the National War Memorial in Ottawa was shot this morning and there are reports of as many as 30 shots fired inside the Parliament by an unknown number of gunmen.  There are reports there are as many as two or three shooters and that one was shot and killed.

Two sources tell The Canadian Press that Kevin Vickers, the sergeant-at-arms for the House of Commons, shot an assailant.

A witness says a man drove up to the Centre Block in a black vehicle, got out carrying a rifle and ran inside.

Witnesses near the War Memorial report that four shots were fired there.

It appears the soldier was shot in the chest, and paramedics could be seen performing C-P-R on him before he was taken away by ambulance.

Prime Minister Harper was on the Hill, but was rushed away to a secure location.

Parliament Hill is under lock down and police have brought in bomb-detecting robots.

Streets surrounding the area have also been cordoned off.  Watch footage from a Globe reporter who captured exchange of gunfire in the Parliament buildings by clicking here
