Amnesty International Accuses Iraqi Shia Militia of Killing Sunni Civilians

Amnesty International says Shia militias in Iraq are carrying out abductions, torture and executions against the Sunni civilian population. A report by the London-based human rights group says the Shia attacks are thought to be carried out in revenge for the brutal actions of Sunni Islamic State fighters in northern and central Iraq. As Henry Ridgwell reports from London, analysts fear a new wave of sectarian violence in the country.
