NATO officials say Taleban militants have carried out 78 suicide attacks in Afghanistan this year, killing nearly 200 people.
Officials say the number of suicide attacks this year is almost four times the number of attacks reported in 2005.The majority of the victims have been Afghan civilians.
NATO says suicide attackers killed 142 Afghan civilians, forty members of the Afghan security forces and 13 foreign soldiers. It says the attacks are part of an intensified Taleban insurgency in parts of the country.
Meanwhile, the Afghan Defense Ministry says Afghan and U.S.-led troops killed five Taleban insurgents and captured one in the eastern province of Paktika on Saturday.
Separately, Afghan police are searching for the gunmen who killed two German journalists early Saturday in a remote part of northern Afghanistan.
The two Deutsche Welle journalists, a man and a woman, were shot dead as they spent the night in a tent in Baghlan province. The motive for the shooting is unknown.
German Foreign Minister Frank-Walter Steinmeier condemned the killings as atrocious and senseless.
