Dec. 15 (UPI) -- Nobel Peace Prize winner Narges Mohammadi spoke briefly with her family by phone Sunday evening and shared information about how she had been detained, according to relatives.

The Narges Foundation said she reportedly was arrested Friday by Iranian authorities.

Mohammadi managed to speak with family after almost three days with no communication.

She was accused of "cooperating with the Israeli government."

The Paris-based human rights organization said that security and police forces "violently detained" Mohammadi and other human rights activists during a memorial for Khosrow Alikordi, a lawyer recently discovered dead.
