THE blast caused by an explosives-laden vehicle that killed a woman and injured five others in GOR II in Lahore on Wednesday has raised many questions. Police sources do not rule out the possibility of Prime Minister Yousuf Raza Gilani being the target, since he was in the city at that time. The tough security cordon around Mr Gilani might have forced the miscreants to change the site of the attack. Though the investigations are in the initial stages the fact that the mini-truck was parked at a stone's throw from the house of a senior police officer, who was responsible for carrying out an operation that led to the death of Lashkar-e-Jhangvi leader Riaz Basra, is a factor that cannot go unnoticed as well. Another thing that should be considered is that it was perhaps the first time that an official vehicle was used by the terrorists. The car, belonging to the Fisheries Department had been stolen about a month ago though it continued to carry official numberplates, which must have facilitated its entry into GOR II. Meanwhile there are also reports indicating a foreign hand in the blast. On account of the calls made in the area, the police have arrested an Indian citizen and is investigating the matter. That urban centres like Lahore and Peshawar, that also happen to be provincial capitals, have come under a spate of attacks in recent times is indeed something quite alarming. The other day PM's Interior Adviser Rehman Malik declared in Parliament that the attack on the Marriott Hotel was carried out by the Lashkar-e-Jhangvi that, among other things, hints at the strength such forces have been gaining over time. What happened in GOR II only points to the vicious spiral of the scourge. It is a sad reflection on the state of our law enforcement agencies that they have not had much success in freeing the country of the menace.
