A 27-year-old female student has been stabbed to death in northern Afghanistan.

Officials said Palwasha Tokhi was attacked with a knife by an unidentified man in her house in the city of Mazar-e Sharif on September 16.

The assailant managed to escape and the motive was not clear.

Tokhi reportedly worked for six years for a media organization before leaving her job to pursue her studies.

Also on September 16, police in the western province of Herat said Taliban fighters killed at least six officers in an ambush.

Six other police officers were wounded and eight Taliban fighters were killed in the assault.

The Interior Ministry says more than 1,500 police have been killed in attacks over the last six months.
