1 policeman among 4 killed in Afghan blast

Four people were killed and three others wounded Saturday in a bomb attack in Jalalabad city, the provincial capital of eastern Afghan province of Nangarhar, police said.
The blast occurred at night when an improvised bomb planted in a garbage box went off through a remote control, a provincial police spokesman, Hazrat Husain Mashriqiwal told Xinhua.
The casualties included one police officer and three civilians, the spokesman said, adding that the dead officer might be the target.
Police launched an operation to arrest the culprits behind the incident, he said.
The three wounded were shifted to a hospital in the city.
The Taliban-led insurgency has been rampant since they launched an annual rebel offensive against Afghan security forces and more than 51,000 NATO-led troops stationed in the country earlier this month.
The war-torn country is due to take over the security responsibility by the end of the year.
More than 2,900 civilians were killed and nearly 5,700 wounded in conflicts and Taliban-led attacks in the country last year, according to figures released by the U.N. mission in the country
