Five days after Canada's Prime Minister Justin Trudeau and his family landed in India, he was given a ceremonial welcome Prime Minister Narendra Modi. After the early morning bear hug, PM Modi later said those who challenge India's unity will not be tolerated. The comment came a day after the Canadian Prime Minister's team drew criticism after convicted Khalistani terrorist Jaspal Atwal was seen at an event where Mr Trudeau was attending. The invitation was eventually withdrawn. Canada has described the invitation to Jaspal Atwal an oversight by its officials.
