On 29 July 1985, the Israeli army imposed a 5-day curfew on the city. At the time this was the longest curfew ever imposed on a Palestinian community in the West Bank. It was lifted 2 hours each day to allow residents to find food. The curfew was in response to the murder of two teachers on 21 July near Jenin and the killing of an Israeli para-military on 30 July. Najah University was closed for 2 months after posters with pictures of PLO leader were found.
