KABUL (TIP): An Afghan official says a roadside bombing has killed three policemen and wounded two in the country’s western Herat province.

District police chief Shir Agha Alokozay says the attack took place in the province’s Obe district today morning, when the police vehicle the officers were riding in hit the roadside bomb.

Alokozay says the bomb was set off by a remote control device and that the police have caught a suspect with the remote control.

No one immediately claimed responsibility for the attack but Afghan security forces are frequently targeted by insurgents and violence has intensified in the country as most international troops prepare to withdraw at the end of the year.
