In the first incident, a group of criminals ambushed a police party in Quetta, as they were preparing to launch a raid
Four policemen were killed in two separate attacks in Pakistan's restive southwest, officials said on Wednesday.
In the first incident, a group of criminals ambushed a police party on a major road in Quetta city, Balochistan province, as they were preparing to launch an arrest raid.
The police driver and another officer were injured and died from their wounds before they could be transferred to hospital.
In a second attack, two gunmen on a motorbike opened fire at a pair of police officers in a minority Hazara Shiite community area as they were going to buy food for their evening meal. Both policemen died at the scene.
Manzoor Sarwar, a senior police official in the city, said that authorities were investigating the attacks.
Another police official Zahoor Afridi confirmed the casualties.
The mineral-rich Balochistan province of which Quetta is capital has been plagued for decades by separatist insurgency and sectarian killings. Hundreds of members of the ethnic Hazara Shiite community have been killed there in recent years.
