A man from the predominantly Bedouin southern city of Rahat has been arrested for posting a video on his Facebook page that called for people to carry out car-ramming attacks, Israeli police said in a statement on Wednesday. The video featured footage from last Sunday’s terror attack, in which an East Jerusalem man drove his truck into a group of Israeli soldiers, then backed up and ran over them again, killing four and injuring dozens. In the background of the video a voice, speaking in Arabic, encouraged people to carry out similar attacks. Police said the suspect, a thirty-year-old Rahat resident, was first detained on Tuesday and would remain in jail at least until  Sunday. ‘While protecting free speech, we cannot allow incitement and threats on Facebook’, the statement said. Earlier in the week, police arrested four residents of the Old City in Jerusalem for spray-painting graffiti praising Fadi al-Qunbar, the driver in Sunday’s attack.
