Quetta: Gunmen riding motorcycles on Monday opened fire outside a passport office in southwestern Pakistan, killing three people, including a police officer, in an attack police blamed on radical Islamist groups.
Police blamed Monday's attack in Quetta, the capital of the restive province of Baluchistan, on militant groups.
A police official, Abdul Razzak Cheema said that Lashkar-e-Jhangvi extremist group was possibly involved.
Lashkar-e-Jhangvi was blamed for twin blasts in Quetta in 2013 that killed around 180 people, mostly civilians.
It was also involved in assaults in 2009 on Pakistan's military headquarters and on Sri Lanka's visiting cricket team.
