Published on Oct 21, 2013 | Amnesty International says the United States should be investigated for war crimes over its drone strike programme in Pakistan. The human rights watchdog investigated 45 drone strikes between January 2012 and August this year. It highlights incidents where civilians were killed in North Waziristan, including the death of a 14-year-old boy. Amnesty also documented cases of so-called rescuer attacks, where those who ran to help the victims of a drone strike are killed in a follow-up attack. Al Jazeera's Imtiaz Tyab spoke to one family that was targeted in one such strike.
