Two Afghan policemen were killed and three others were wounded when their vehicle hit a roadside mine Tuesday on the Spin Boldak highway of southern Afghanistan's Kandahar province, said a police official.
Sakhid Jan, the Spin Boldak highway police chief, told Xinhua that it occurred at 9:30 a.m. (0500 GMT) when a team of police were patrolling along the highway.
"The explosion was only 5 km from the city center, killing two highway police and injuring three others," Sakhid added.
The police official did not disclose who was behind the incident.
Over a dozen of Afghan police have been killed in the past three days while Taliban militants recently have vowed to launch the "Spring offensive" to intensify their guerrilla-style attacks on national army and foreign troops.
However, Carlos Branco, the ISAF spokesman recently termed Taliban announcement as mere propaganda and downplayed it, saying Taliban had lost capability to face NATO and Afghan troops. Instead, it began attacking soft targets and killing civilians.
