Prime Minister Narendra Modi described Wednesday's shootout near the Canadian parliament in Ottawa as "extremely disturbing".
"News of the attack in Ottawa is extremely disturbing. I pray for everyone's safety," he tweeted.
Parliament Hill in Canada's capital Ottawa came under attack on Wednesday after a gunman shot dead a soldier standing guard at the National War Memorial, a day after Canada sent an air fleet consisting of CF-18 Hornet fighters in support of the efforts to fight against the Islamic State (IS) terrorist group in Iraq and Syria.
MPs and other witnesses reported 30 to 50 shots were fired inside Parliament, and a gunman has been confirmed dead inside the building, shot by the House of Commons sergeant-at-arms, according to the MPs' accounts, CBC reported.
