Murad Mahmoud’s 14-year-old son has been detained by Israeli police in his east Jerusalem neighborhood three times in the last two years. Nearly every day for the last nine months Israeli police have stormed into the Palestinian neighborhood of Issawiya in east Jerusalem in a campaign they say is needed to maintain law and order. Rights groups say that in addition to searching houses and issuing fines, they have detained hundreds of people — some as young as 10 — on suspicion of stone-throwing.
