Sources confirmed to KabulNow that the Taliban arrested Rasul Abdi Parsi, a former lecturer at Herat University, in Kabul 20 days ago. However, his whereabouts and fate remain unknown.

Parsi was arrested for criticizing the Taliban on his Facebook account as he continued to write posts critical of the Taliban performance, his friends told KabulNow on Tuesday.

He had formerly taught Islamic sharia or Islamic laws at Herat University and has been living in the capital Kabul for a while.

Some university lecturers and his friends have launched a campaign in western Herat province for his release from Taliban custody. They warned that his life is at risk.

The Taliban has not commented on his arrest. The group has recently increased the arrests of activists, protesters, university lecturers, journalists, and human rights activists in recent months.

In the latest case, the group arrested Matiullah Wesa, an education campaigner, from Kabul on Monday. His arrest drew widespread reactions and calls for his release.
