A police official told media that the operation was carried out in order to neutralise terrorists involved in attacks on security forces.
The law enforcement agency carried out the operation jointly with the Frontier Constabulary men. As the security personnel surrounded a house in Kuchlak, they were fired upon by the terrorists, resulting in the casualties.
The police fired back, killing one terrorist, whose body was moved to a hospital to ascertain his identity.
The LEA said arms and ammunition were recovered from those killed, suspecting their involvement in Monday's terrorist attack.
A day earlier, four people — including two police personnel — were killed while another 15 sustained injuries in a blast targeting a police vehicle near Qandhari Bazar of Quetta’s Shahrah-e-Iqbal.
The reports in the media quoted a senior police official as saying that a police vehicle was the target of the blast.
He added that the explosives had been planted on a motorcycle, adding that the injured include women and children.
The injured were rushed to Civil Hospital Quetta for treatment, and the death toll is feared to rise.
“About three to four kilogrammes of explosives were used, damaging two vehicles, including a police van,” the official said.
Last month, an explosion near a Balochistan Constabulary van near the Kanbari bridge in the Kachchi area of the province resulted in the death of nine security officers and the injuries of 13 others.
Also, on February 26, an explosive-laden motorcycle explosion caused at least four fatalities and 12 injuries in the Balochistan Barkhan district.
In a recent key meeting of the National Security Committee (NSC), it was resolved that a fresh military operation, a full-fledged one, is the need of the hour to tackle the rapidly growing terror threat.
