- 4 people are killed in an attack in southwest Pakistan
- 2 of the victims are police officers
- The attack is part of a wave of sectarian violence
Four people -- including two law enforcement officials -- were killed in southwest Pakistan Wednesday when suspected militants opened fire on a police patrol car, according to a senior local police official.
The suspected militants were riding on a motorcycle when they started firing on the car, Fareedullah Bareech told CNN.
The attack -- which occurred in the provincial capital city of Quetta -- is part of a wave of renewed violence in Pakistan, including the recent killing of 14 Shiite Muslims on a bus. Seventy-five suspects have been arrested in connection with the bus attack.
Violence between various Sunni and Shiite factions has claimed countless lives near the Afghanistan-Pakistan border over the past few months.
