(CNN) -- Taliban militants attacked a checkpoint in southern Afghanistan late Monday, killing at least six police officers, authorities said.
The attack took place in the Arghistan district of Kandahar province, according to Border Police commander Rahmatullah Khan. He said police inflicted casualties on the Taliban fighters, but had no details.
Qari Mohammad Yousif Ahmadi, a Taliban spokesman, said the group's fighters were responsible for the attack, but had suffered no casualties.
Meanwhile, two foreign nationals were missing in western Afghanistan's Herat province, police and diplomatic sources said.
Authorities feared two Indian workers had been kidnapped by an unknown group in the Adraskan district. A police spokesman said a taxi they had been traveling in was found abandoned.
An Indian diplomat in Kabul said the missing were an Indian citizen and a Nepalese, who hadn't been seen since Monday night. He said Afghan forces are searching the area. E-mail to a friend
