The head priest's son Sazid Ali Nizami said his father and 60-year-old cousin had gone to Pakistan on a pilgrimage to the famous Daata Darbar shrine in Lahore and were to fly to Karachi from there yesterday. His family's last contact with his father, he said, was from the Karachi airport.
"On March 14, they offered another 'chadar' at Daata Darbar sufi shrine in Lahore. The next day, they reached Lahore airport to take a flight to Karachi at 4:30 pm. At the Lahore airport, my cousin was stopped by authorities to clear some documentation and my father was asked to board the flight," Sazid Ali Nizami told news agency IANS.
He said that their mobile phones have been switched off since. "We have no information as such. We have been putting up our landline numbers in advertisements," he said.
The two clerics had already visited Karachi earlier this month to meet their relatives before travelling to Lahore.
