Following the blast that shook the CTD police station in Swat's Kabal a day earlier, the police declared in the preliminary investigation report that "no evidence of an attack from outside has been found."
More than 40 people were injured by the explosion and are currently receiving medical treatment, according to the police, who also verified that at least 16 people were martyred.
According to the police investigation, "there is a high likelihood that the blast was caused by a short circuit as fire erupted in the armory."
While addressing the media CTD DIG Khalid Sohail said that carelessness was to blame for the ammunition's fire. He disclosed that the incident occurred in the CTD's former office.
He also ruled out the idea that the blasts might have been terrorist strikes or other types of suicide bombings.
"There was a store where we stored a large number of weapons, and as of now, we think there may have been a blast there as a result of some negligence," he added.
According to Sohail, the shock waves "completely collapsed the building."
As the rubble removal process continues, neighboring structures, including mosques, homes, and schools, as well as their walls and roofs, are also being repaired.
Twelve police personnel and four civilians were martyred in the incident. According to the hospital administration, ten of the 40 injured people are in critical condition.
The explosion was followed by two to three bomb blasts, according to Khyber Pakhtunkhwa Police Inspector General Akhtar Hayat Gandapur. He continued by saying that "the majority of the victims" were police personnel.
Prime Minister Shehbaz Sharif initially labeled Monday's explosions as a "suicide attack" on Twitter. He stated that "our police have been the first line of defense against terrorism."
He posted an update late at night with the message, "The nature of the blast is being investigated."
