Supporters of a prominent university professor, and one of Afghanistan’s most vocal critics of the Taliban, are calling for his release after he was arrested on Saturday.

Faizullah Jalal, a professor at Kabul University, was detained by the Taliban after the group claimed he was responsible for a series of messages on social media attacking them.

Taliban spokesperson, Zabihullah Mujahid, tweeted: “A fanatic named #Jalal has been arrested for his remarks on social media inciting people against the #system and playing with human dignity,” adding screenshots of posts from a social media account with Jalal’s name and photograph.

But his daughter, Hosna Jalal, said the accounts listed by Mujahid are fake. “We had in fact reported them to Twitter a week prior, but they didn’t take any action. We have emails to prove that,” she said.

Hosna, who is currently studying in Europe, said she first learned of the arrest from social media. “We don’t know where he is being held or how he is doing. The Taliban have refused to let us talk to him. We were able to confirm the news through friends who were with him at the time of the arrest,” she added.
