Two people have been arrested over the killing of an Indian woman, who wrote a memoir about her escape from the Taliban, in Afghanistan.
Sushmita Banerjee was shot dead by suspected militants last Thursday.
The police chief of Paktika province told the BBC that the arrested were member of the Haqqani militant network.
According to the report, Banerjee had recently moved back to Afghanistan to live with her husband, an Afghan businessman.
A senior police official said that Banerjee was working as a health worker in the province and had been filming the lives of local women.
She became well-known in India for her memoir, A Kabuliwala's Bengali Wife, which recounted her life in Afghanistan with her husband and her escape from the country after the Taliban takeover, the report said.
She was also the subject of a 2003 Bollywood film, Escape From Taliban, it added.
