Rajapaksa, who was earlier scheduled to leave the Himalayan nation on Wednesday, cancelled his visit to Lumbini, the birthplace of Lord Buddha, and will fly back to Colombo on Tuesday evening.
Rajapaksa is cutting short his visit and leaving Kathmandu because of the attack in Lahore in which six players and a coach of the team were injured, Sri Lankan embassy sources said.
He had earlier instructed Foreign Minister Rohitha Bogollagama to immediately rush to Pakistan to oversee the arrangements to bring the cricketers back to Colombo.
