"The suicide attack at Wagah looks like a security lapse and I will ensure this does not happen again, particularly when over 2,000 Sikh pilgrims arrive at the Wagah railway station.
"I have also urged Railways Minister Khawaja Saad Rafique to check the trains, which will bring all the pilgrims," Farooq was quoted as saying.
Farooq said it was possible that the target was the main ceremony area, where a large crowd had gathered.
"The suicide bomber was stopped at the second of two checkposts leading to the ceremony area, where he blew himself up. It was possible that the terrorist reached the spot through the nearby fields."
