The death toll in the suicide attack targeting one of Pakistan's oldest and most revered Sufi shrines in Lahore has risen to 13 as another civilian succumbed to his injuries, a media report said Monday.
He was rushed to the hospital after the blast which has claimed the lives of six policemen and seven civilians, the Dawn newspaper reported.
A senior police official told the daily on condition of anonymity that security forces had yet to make any substantial progress in the investigations into the attack.
He said that although they had arrested a few suspects from Lahore, they were no big leads.
A CCTV footage showed a teenage boy wearing black shalwar kameez and a suicide vest coming closer to the vehicle of elite force beforing blowing himself up.
Punjab Inspector General of Police Arif Nawaz has said it was a suicide attack as the target was the vehicle of the elite force that was stationed outside the shrine of Sufi saint Ali Hajvari commonly known as Data Darbar.
"Police was the target. 100 per cent," he said.
The rickshaw used to transport the suicide bomber to the shrine has been identified, he added.
The CCTV footage shows the rickshaw driver approached the bomber as the latter emerged from Garhi Shahu area, some seven kilometres from the shrine.
The famous shrine is visited by hundreds of thousands of people each year. In 2010, the heavily-guarded shrine was targeted in a suicide attack that killed more than 40 people.
Police also confirmed that Hizbul Ahrar had claimed responsibility for sending the teenage suicide bomber to the shrine.
It started operating separately to target primarily the law enforcement agencies in various parts of Pakistan, the police said, adding the CTD is also following other leads, like the possibility of the involvement of Islamic State terror group.
