Prime Minister Narendra Modi has expressed serious concern over the attack on Canadian parliament in Ottawa, terming it as "extremely disturbing." 

"The news of attack in Ottawa is extremely disturbing. I pray for everyone's safety", Modi tweeted. 

Canada's Parliament came under attack today with a barrage of gunshots fired both inside and outside the building as a soldier was killed in the assault and a man with a rifle was shot dead by security forces.

Parliament Hill came under attack when a man with a rifle shot a soldier standing guard at the National War Memorial in downtown Ottawa, before seizing a car and driving to the doors of the building's Centre Block nearby.
