Lahore: Ten people are reported dead and more then twenty injured in an explosion in Lahore’s defense area Y Block Market on Thursday in an under construction building.

The blast took place inside an under-construction building where laborers were present inside when the explosion took place. An entire floor of the building collapsed because of the blast. Four cars and 12 motorcycles were also damaged, while the windows of nearby buildings were shattered, Said DIG operations Haider Ashraf

Chief Minister Punjab Shehbaz Sharif has ordered an investigation of the blast and summoned a report from Inspector General Police.

“An investigation will further reveal if the target was the café,” a CTD official told reporters. He added that the forensics team was collecting evidence and a complete picture would be shared when the investigation was complete.

But later in the evening, CTD Punjab spokesman Dr Iqbal Malik said the blast was accidentally caused by 7 to 8 gas cylinders which had been brought to the restaurant last night.

Government officials and investigators appeared equally confused over the nature of the explosion.

No terrorist group has so far claimed responsibility for the explosion
