Taliban militants killed 19 Afghans, including seven civilians, and wounded 41 more in a suicide bomb attack on a drug eradication team in eastern Afghanistan today, the Interior Ministry said.
The Taliban have vowed to step up suicide attacks this year, to undermine the faith of Afghans in the ability of their government to provide security and to sap support in the West for the continued presence of international troops in the country.
The bomber targeted an opium poppy eradication team led by the district chief, tribal elders and police officers as they left the local government headquarters in Khogiani, a town south of the city of Jalalabad, close to the Pakistan border.
Gunmen opened fire with small arms and rocket-propelled grenades following the suicide attack, the NATO-led International Security Assistance Force (ISAF) said.
Twelve police officers and seven civilians were killed, the Interior Ministry said. Two Australian journalists were also among the wounded, the ABC broadcaster said on its website.
"This event proves that ... cultivation and production of narcotics in Afghanistan is inseparably related to terrorist forces," the Interior Ministry said in a statement.
Afghanistan last year produced 93 per cent of the world's opium which is processed to make heroin and exported to the West.
Illegal drugs could be worth more than $3 billion a year to the Afghan economy, and United Nations drug experts say the Taliban impose a 10 per cent tax on poppy farmers who produce opium and also on the drug traffickers to finance their insurgency.
Drug production is highest in the areas of Afghanistan where the Taliban are strongest, but the Afghan government has made progress in eliminating poppy crops in some areas, such as around Jalalabad, where it has tightened its grip on security.
The Taliban launched more than 140 suicide attacks across the country targeting foreign and Afghan government forces last year. Most of the victims, about 200, were civilians.
The conflict has steadily picked up in the south and east in recent weeks as Spring arrives and mountain snows melt.
