PESHAWAR, Pakistan -- Unknown assailants have killed four policemen in northwestern Pakistan's restive Khyber Pakhtunkhwa Province.
RFE/RL's Radio Mashaal reports that gunmen riding on motorcycles shot the policemen, who were manning a checkpoint late on the night of October 20 on the outskirts of the provincial capital, Peshawar.
Relatives of the slain officers later protested. They blocked a major thoroughfare in Peshawar by placing the bodies of the police officers in the road.
The relatives criticized senior police officials and the government for failing to put an end to the frequent murders of law-enforcement officers in the region.
No one immediately claimed responsibility for the shooting, but Pakistani Taliban factions routinely target the police and security forces.
More than 50,000 Pakistanis have been killed in the decade-old Taliban insurgency.
Train Bomb Kills At Least Five
Also in Pakistan, a bomb targeting a passenger train in the southwest of the country has killed at least five people and wounded 17 others.
Officials in the restive province of Balochistan said on October 21 that the bomb was apparently planted on the rail track in Naseerabad district.
The train -- called the "Jaffar Express" -- was traveling from the northwestern city of Rawalpindi to Balochistan's capital, Quetta.
The explosion derailed the train.
The vast desert region of Balochistan is suffering from a separatist insurgency, sectarian violence, and a harsh military crackdown.
Baloch rebels have waged numerous insurgencies since Pakistan's creation in 1947.
The latest insurrection began in 2004 as Baloch rebels demanded political autonomy and control over the region's profits from its oil, gas, and mineral resources.
