A growing nexus between Al-Qaeda and banned Pakistani Sunni extremist outfit Lashkar-e-Jhangvi was suspected to be behind several of last year's sectarian attacks in Karachi, police officials said.
After investigating the three bomb blasts that took place in Karachi in 2006, the police were concerned over links among LeJ and Al-Qaeda and the Abdullah Mehsud-led terrorist group which was active in Waziristan, Daily Times reported on Monday.
Investigations revealed that the bomb attack in the US Consulate in March last year, killing diplomat David Foy and three others, was carried out by a suicide bomber named Raja Mohammad Tahir, a Karachi resident with links to Al-Qaeda who underwent training in Afghanistan and Wana in Waziristan.
The second suicide bombing took place about a month later, on April 11, at Nishtar Park at an Eid Milad-un-Nabi congregation killing over 60 people, including the entire top hierarchy of the Sunni Tehreek (of Barelvi school of thought).
During probe, police, who termed it the biggest terrorist attack of the year, began to suspect that it was a sectarian attack. "Till now this case could not be solved completely. But what has surfaced is that the Nishtar Park bombing was about a sectarian clash," a senior official told the paper.
The police also believe that prominent Shia cleric Allama Hasan Turabi was killed along with his nephew in Karachi by a Sunni extremist. Police identified the suicide attacker as a 16-year-old of Bengali origin named Abdul Karim from Karachi.
The police followed clues that took them to Wana in this case, leading them to conclude that the LeJ, al-Qaeda and the Mehsud-led group were behind the killing.
