A suicide car blast that took place Tuesday morning in Pakistan's eastern city of Faisalabad killed at least 13 people and injured some 50 others, reported local media.
According to the reports, the blast occurred at about 10:15 a.m. local time when an explosive-laden vehicle tried to force into an intelligence office building located at the Civil Lines area of the city, some 100 kilometers southwest of Lahore.
Local media quoted the city's District Coordination Officer Naseem Sadiq as saying that the blast happened when gunmen guarding the gate of the intelligence office building shot back at the terrorists in the vehicle.
The blast also led to another explosion of a nearby CNG station. At least a dozen cars were destroyed in the two blasts and a lot of buildings nearby were also damaged, including a Pakistan International Airlines office building adjacent to the intelligence office building.
One local media report quoted eyewitnesses as saying that at least 15 people were buried under the debris of three completely destroyed houses nearby the blast site. Rescue workers are now trying to save the people buried under the collapsed buildings.
Police sources said one of the terrorists involved in the blast was arrested and the injured terrorist had been shifted to a nearby hospital under the police escort. It is not known yet how many terrorists were involved in the attack.
No group has claimed the responsibility for the blast yet.
