The Shin Bet security agency said that Shifa al-Qudsi was barred from entering Israel from the West Bank for "security reasons."
In 2002, Al-Qudsi was preparing to carry out a suicide bombing when Israeli troops arrested her. She spent six years in prison, and after her release, got involved with "Combatants for Peace" a group that seeks to end violence between Israelis and Palestinians.
Al-Qudsi is one of the activists featured in the documentary "Disturbing the Peace," which premiered at the Jerusalem Film Festival today.
