Canadian journalist Josh Wingrove has tweeted a minute-by-minute account of a shooting in Canada’s parliament which saw two men killed.

The Globe and Mail reporter was inside the national parliament in Ottowa when a gunman stormed the building, following the shooting of a soldier at a nearby war memorial.

The gunman was fatally shot by Canadian police after exchanging heavy gunfire inside the halls of parliament.
